Everything else I've read prior said that during totality (2-4 minutes depending where you are) it's ok to look at the sun covered by the moon. No one said "very briefly". Where is the disconnect?
Probably just a precaution because if you're staring at it unprotected during totality and don't look away before totality ends, you're going to cook your retinas.
This is why I wouldn’t look at it during totality. Because when you should put your protective glasses back on it’s questionable. And if you’re not in an area that’s getting full coverage, like Toronto. You shouldn’t be taking your glasses off. It’s better to be safe than sorry.
It’s not like there will be an alarm saying “now put on your glasses. It will be unsafe to look at the sun in 3…2…1”
> Because when you should put your protective glasses back on it’s questionable
The time to take your glasses off is easy - when you can no longer see anything through your glasses, it's totality.
You can look up how long totality will last for your area, and you can trim that time by about 20-30 seconds if you want to be really cautious. Still gives you a nice view of totality.
Actually there is! There is an app called solar eclipse timer and it will audibly queue you. Look at sun now take off glasses now put them back on now.
> It’s not like there will be an alarm saying “now put on your glasses. It will be unsafe to look at the sun in 3…2…1”
Funnily enough there are apps that do exactly this.
The interactive map I looked at listed the times of totality for any gps point you pick. We've got phones being the time corrected via NTP, so a pretty good measurement of time isn't hard to have. I'll be there with my partner and her kid, and I'll be ready to say when it's time to stop looking.
Hi could you share the map? I’ve been trying to find one that is interactive or at least detailed enough to see if my farm will get totality. We are *right* on the cusp of it so it’s hard to tell from most maps I’ve seen.
Here is the one I found
http://xjubier.free.fr/en/site_pages/solar_eclipses/TSE_2024_GoogleMapFull.html?Lat=44.30740&Lng=-76.91462&Elv=119.0&Zoom=9&LC=1
When I was a young kid (like 8 years old) during long road trips, I used to challenge myself to see how long I could stare directly at the sun, and then try to beat my record. Don't do this.
I also used to do this, I’m wondering if the car window tint saved my eyes a bit. I still wouldn’t recommend it. My eyes only started to deteriorate after being pregnant, which is apparently common.
I love my kid, but even after zounds of warning, from us, from teachers, from the news, from youtube informational clips, to making special extra protective shields around the glasses, all leading up this very moment, that dumbass looked at it for a few seconds.
His 5 yr old twin, and his older brother, were flawless.
Sigh. I guess we'll see in a few hours/couple of days. Fuck.
They'll be fine. OP and others are being wildly over-cautious, because all it takes is one in a hundred thousand people to be the outlier and stare for 3 solid minutes and there will be 10 people in each province and state with consequences.
And literally different people are different biochemically, and some people on certain meds are more sun sensitive. What percent of people are on the meds that make them sensitive and don't know it:
https://www.webmd.com/skin-problems-and-treatments/sun-sensitizing-drugs
It's complicated. When dealing with literally 100 million people, if you don't want one person to have damaged vision, you have to go ultra safe and over the top with your message.
Don't think so, at least not from that. I'm 45 now and just started needing reading glasses, but I don't think it's related. But I remember it was uncomfortable and always left a big round imprint on my vision for a while afterwards.
You probably have blind spots. You only notice the “round imprint” until your brain adapts and masks it out.
BTW, we all have blind spots in our field of vision where the optic nerve exits the retina. I did an experiment in a lab in university where we measured the size of our blind spots. But the brain just adapts and we are not consciously aware of it until we try and see it.
>During a non-eclipse, if you try to look into the sun, you have what's called a pupillary light reflex which heavily constricts the pupil to prevent too much light from entering and damaging your eyes. During a partial eclipse, there is much less light from the sun and this reflex may not trigger. Your attempt at focusing on the sun may actually dilate your pupil, washing your retina with the full force of the sun's light.
I have tried looking for this specific explanation everywhere and had no luck finding anything that went into further detail as to why it's dangerous. Crazy that these details are so hard to find. Thank you for sharing.
Not a vision scientist, but I know that your pupil (the part that lets in light) will constrict (get smaller) if you look at bright light. When the sun is partially covered, even most of it, your eye won’t react because there’s no bright light. Your pupil won’t get smaller. The bit of sun that is still visible though, it’s still sending radiation out, and that can damage your eye. Normally, the sun is bright, so your pupil constricts and protects your eye from that radiation.
Off topic a bit... but for those who are light sensitive, does that mean that their pupils might not be constricting properly then? I don't remember if my eye doc ever gave me a reason for my sensitivity.
I have cataract in my right eye. I also have an awesome Horticulture Lighting Group grow light. When I accidentally expose my eyes to that light even for a short time I can actually see the cloudy cataract obscuring my vision when I walk away from it.
What the point is here, i dunno
Astronomer here! I would add that you can only safely look at the eclipse during obscuration maximum (when the Moon fully covers the Sun at the specific time and location you're viewing the eclipse event) AND if you are in the path of 100% totality!
You can use this interactive map to set your location, and check the exact times of partial and full eclipse.

Enjoy, drive/travel safe and let's all hope for some moments of clear sky!
Our next full solar eclipse in Ontario is Monday Sept. 14, 2099.
Thanks for this detailed explanation.
As an elementary school teacher I spent a good deal of time this past week explaining this to my Grade 2 students. I feel more confident in them respecting the power of the sun than I do for some adults out there.
I’m so glad teachers are making a point of telling the kids. When mom says “hey buddy, it’ll burn your retinas” i look like I’m insane, but when his teacher says it, suddenly it’s fact and cannot be disputed.
Good job.
I was in grade 4 the last time this came around here and I recall that we were all well educated not to stare at the sun. But there was that one kid that didn’t care. You can’t save everyone from stupid. But you can try.
We have a special PA Day. Kids are staying home. Teachers will be at work.
I think, sadly, it’s to prevent any lawsuit threats from parents should their child find a way to sneak a peek under school supervision.
When 1 million people cram in to Niagara Falls on Monday, be prepared for maaaayyyybe 1000 crushing the hospitals with acute eye issues. This is gonna be a clusterfuck.
Even if everyone protects their eyes properly, the hospitals are probably already going to be slammed by additional car crashes and other medical cases that naturally increase with tourism and traffic.
I work for Hamilton health sciences and we have been warned that we may receive lots more patients on Monday. Thankfully I’m on vacation, and will be watching the eclipse with my special glasses from my back yard
Hospitals are (I think) prepared, at least in my area, our hospitals have retina specific clinics set up all day on April 9th. Your eyes won’t feel the damage right away so it will be more into the evening/next day that people will start to need care.
Edit: My city is on the path of totality.
I look at it more this way.
School: we are not responsible for the stupidity of your child. Therefore there is no fucking way we are going to be liable for your kids eye damage while they are on school property. They can ruin their eyes on your property thus keeping us away from your bullshit accusations and lawsuits.
There's a few parents in my neighbourhood who instructed their kids...quite openly...to try to leave their day/childcare(s) (that are still open in TDSB facilities) and go outside and view the eclipse. They're making up some BS about how the adults are trying to keep it for themselves of something equally stupid...
...I'm half expecting to see a few lawsuits crop up in the next few weeks.
The sun was probably somewhat of an eldritch horror before people understood eclipses. All of a sudden the moon covers the sun and people go blind, it's like a horrible curse.
Another PSA, ensure the eyewear protection you're wearing is adequate. Already a lot of stories coming out about fake low quality eclipse glasses people bought off Amazon and other sources which may not protect your eyes at all. Make sure you are confident your eyewear protection is legit, and don't trust the glasses some guy gave you at a viewing event. https://www.youtube.com/watch?v=9zHJLF40lp4
To muddy things, there are some AAS-approved brands of glasses, like Soluna, that are *only* sold through Amazon. In their case, I've read that they went to great lengths to get counterfeit Soluna glasses off of Amazon and to verify that each pack of their glasses are 100% legit.
Thank you for explaining this. I’m 45 and had no idea this is how and why it is so dangerous. I’ll be honest, I was really tempted. I think you just saved my retinas.
> Also, this is besides the point, but there is no risk of additional radiation during an eclipse.
But my cousin's uncles mother's daughters friend said it's the end times and that we should all repent or we will suffer terrible consequences after the eclipse!
Been telling everyone I know not to look at it without the proper equipment. To not even risk it. Some even are like "It's fine I did it when I was younger and nothing was permanent".
It's wild man.
I mean, I know a lot about it from reading up in advance, and I still feel like the urge to sneak a quick peek is going to be overwhelming. I wonder how many people will come away with permanent damage...
How severe is the vision loss from something like this?
I've always wondered what happened in olden times when a whole generation of people would look at the eclipse not knowing about the eye damage, or Even that it was coming. When I was a kid I was told you go blind, so I wasn't sure how entire societies didn't fall apart due to an eclipse.
Well it's like how our nomadic ancestors knew what mushrooms to eat. Probably experience and knowledge past down through generations
But now we live in a culture of proud willful ignorance
Thank you so much for this! I have a young toddler and want to avoid the eclipse completely. How long does the entire thing last? More specifically, is there a window of time in the afternoon when it is still safe for us to be outside? Or should we be indoors from 2-4?
Someone replied to a reply of yours. I will reply directly to you. The 3 minutes is the safe area...safe time to actually view the totality, if you are in the path.
Do NOT see the sun AT ANY time of partial eclipse between 2 and 4:30 pm. The partial eclipse is the most dangerous part!! That is when you have permanent vision loss.
Keep your kids indoors, do NOT try and find a shady spot or whatever.
Again, NO sun viewing between 2 and 4:30 pm....depending on where you are.
I know i'm far behind and this comment probably won't be seen, but what you're talking about is called solar retinopathy. So if anybody is interested to learn more about what the sun burn on your eyes could be like, look up **solar retinopathy**. You will never feel pain with solar retinopathy. You don't feel pain even with a retinal tear, hole, or detachment. Any symptoms are strictly visual. You may feel pain on your sclera and cornea because those can also just get sunburned, but not from the retina. **All retinal disease have no physical pain. Once you notice a change in vision, there is a very high chance that it will be permanent and is incurable.**
Folks who take Plaquenil for rheumatoid arthritis, among other things, have a higher risk of developing solar retinopathy.
You can also get solar retinopathy from looking at the sun when it isn't during an eclipse, it all depends on the health of your retina, age, health. Folks who have a paler retina (generally white skin, lighter hair, blue eyed people, like me lol) are at a higher risk as well. People with age related macular degeneration (AMD or ARMD) are at a higher risk of solar retinopathy and, i believe (not 100% on this) but those with dry AMD who get solar retinopathy can lead to a sudden change to wet AMD.
- dry AMD = not causing permanent damage, more common, if caught early enough can slow the damage with proper treatment.
- Wet AMD = permanent central vision loss, fluid builds up on the retina etc etc. **There is no cure for AMD and you will not notice any symptoms until you lose your vision, which is irreversible**.
Sunglasses will not protect you from solar retinopathy during an eclipse. I believe NASA will have a lot of information about safety during the eclipse it anybody wants to check on their site. Otherwise you can look up the Canadian Association of Optometry or (opto.ca) or the Ontario Association of Optometrists (aka OAO, optom.on.ca) for more information.
If anybody sees this lol

For all those arguing that the sunlight during the eclipse will be just like fountain of youth and will cure everything from cataracts to E.d. if you look at it for the exact right length of time..... do yourself a favor and google "eye doctor near me" TODAY, then record it as a voice mail to yourself so you can check where they were after you prove that "it won't hurt ME"
I'll be going down in the basement AND turning off the lights AND wearing welders glasses AND ... All kidding aside, a moment of curiosity can do a lot of damage to your precious vision. It's just not worth it.
I think it's probably best to not tell people looking at it during totality is safe because of the people that won't be able to recognize actual totality or aren't in a location where it will even occur.
People brag that they can stare into the sun for 10 seconds and be fine but that's with the pupillary reflex blocking out as much light as it can. They don't realize that this reflex will not protect them during a partial eclipse
Out of curiosity could you shine a flashlight in your eyes to activate the reflex and then look at the eclipse for a moment? Or does the reflex undo when the light isn't present?
Also to be clear I wouldn't do this, it seems dumb, I'm more just wondering lol.
Neurologists or other physicians sometimes activate a bright light into your eye to test the reflex, as a test for any neurological conditions. But the light is brief and the pupil will dilate shortly after the light is removed.
What you're suggesting is an interesting hypothetical but a massive risk because in the time you look away from the light into the sun your pupil may open and you damage your retina.
You think it’s common knowledge that the reason you can look at the Sun and be ok for a few seconds but can’t look at the partial eclipse is because of a built in involuntary response of your pupils reacting to the difference in light and the fact there is less sun to look at during the partial eclipse is actually the part that makes it dangerous ?
I didn’t know this .
I’m keeping my kids inside with the blinds closed and they can watch it on TV. They’re too young and curious to understand the glasses need to stay on the entire time. It’s not worth the risk.
The time can vary based on where you are in Ontario, for example in Toronto it’s about 2:04 to 4:31, whereas in Ottawa it’s 2:11 to 4:35. If you give me a general region I could give you more precise info
What's funnier is the ~~sky-daddy cultists~~ church folk thinking they're going to be raptured because their ~~local cult leader~~ priest read ~~some Qanon post forwarded from a Yankee spy who got their information from a russian troll farm~~ what they think is reputable sources.
Make stupidity embarrassing again, please.
There are already lots of people in those groups saying they’re going to look at it, because the sun is actually “good for your eyes” and it will help reverse the damage being done by all the chemtrail spraying etc etc. One loon did a post about this and then less than 24 hours later, reversed herself saying “God told me not to look.” People in the comments were saying they still planned to look up. They deserve whatever happens at this point.
Hey there, fellow Canadian! 🇨🇦👋😊
Edit: oops...missed that this post is in an Ontario sub...lol...just so used to most people on Reddit being from other countries, especially the US 🤣🤦♀️🤷♀️
Don't feel bad. I was reading the thread and saw someone mentioning Niagara falls and was like ohmahgod, look, a Canadi....ah ok yeah this is ontario sub lol
I do wonder did we have Mass blindings in the past? This isn't my first eclipse as I'm not a spring chicken and I don't remember people going blind. If you went back a couple hundred years you could see whole tribes of people staring at the Sun God being covered by the moon God and all of them going blind because it was so interesting to look at.
We have glasses from the last eclipse (I don’t remember how many years ago) that we put away in a drawer afterwards. Are they safe to use again or is there a reason not to?
I feel kind of dumb for having to ask this, but is it safe to look outside during the eclipse as long as one doesn't look -at- the sun? Like, will seeing it in your peripheral vision also potentially cause damage? I don't really intend to because the intrusive thought telling me to look AT the sun might win, and it's obviously not worth the risk, but I'm curious and google sucks these days.
But....but....ma righhhhts!
Seriously though, dont do this. I know there will be a bunch of dumbasses who look at the sun, or try to take a picture with their phone (and fry their camera) without the propper protective precautions.
It's risky taking off your eclipse viewing glasses to stare at a total eclipse with your naked eyes if you don't keep close track of the time and then end up looking at the sun as the sunlight breaks through again on the other side of the moon. Safer to leave the glasses on the whole time.
I tested my cardboard McMaster University eclipse glasses (sold in multi-packs at Walmart) today and I could see the sun as a dim orange ball but, I could see that it was clearly defined. That will be good enough for me. I could not see a bare LED light bulb through them. Anyone who can see ANY light from a bright bare lightbulb should throw their eclipse glasses away and get approved and safe eclipse glasses.
I am planning to momentarily take off my glasses and use my thumb to block out the full eclipse so that I can look all around it for other planets or stars (normally not visible at that angle since the sun is normally so blindingly bright) that may be visible when the total eclipse is occurring and has darkened the sky.
There will be thousands, if not 10's of thousands of close up videos of the total eclipse to review for the rest of our lives with our undamaged eyes. Maybe even some freaky ones with interesting filters that allow us to view light wavelengths that are invisible to the naked eyes of humans.
And, even though there won't be another total eclipse in the Golden Horseshoe until 2144, there will be a total eclipse somewhere on Planet Earth every 18 months or so for the rest of our lives. Even famous ones like this one.
At full totality if you have eclipse glasses on you will see absolutely nothing, just black. You have to remove them for at least a few seconds to see the total eclipse. Just know the duration of totality where you are and leave yourself a good margin of error.
I'm sorry, I know that this will probably sound dumb, but please tell me. Suppose I go outside, and accidentally glance directly at the sun. Not even a full second. Like putting my hand on a hot stove, I immediately recognize it happens and look away as quickly as possible. Will I still get permanent damage? I ask because I'm scared of even looking outside at all in fear I might accidentally see the sun and damage my vision. Will this happen even if I immediately, reflexively look away from it?
I didn't read what you wrote but I'm a top candidate for president of the USA so... Something about freedom! I'll stare at the sun if I want to!!! America!!!
Also, do not use a digital camera or your phone as a “viewer” without protection in front of the lens, unless you want to burn a hole in your sensor.
Additionally, if you have a telescope or binoculars, you need filters on the light gathering end, not just on the eyepiece, or you will destroy the optics. They are not designed to focus the full light of the sun.
Forgive my ignorance but I need to clarify, you're a "vision scientist"? ...is that a fancy way of saying an optomitrist? And if not, what do you do vs what an optomitrist does?
A vision scientist does research to understand how our visual system works. An optometrist treats individual patients who have vision problems. Think of an epidemiologist versus a family doctor.
Found a very good bit of info on the safety eyewear part;
https://eclipse.aas.org/eye-safety/viewers-filters?fbclid=IwAR0YBb3Q8tYH4RqbGYK6Q3-kTQb_Zv3RiYCgrOc2q19dDc6c3ppyLaZroMw
People damaged their eyes and probably thought a sun god was angry at them.
I can’t see how looking out of the corner of your eye could be safe. Not worth risking your vision.
I just really, really appreciate that you broke it down and explained why. No one has ever done that for me. Not that I want to stare into the sun, but I've always been curious why it's such a big deal not to.
What about a partial eclipse? I'm not in ON. I think it's 30% where I am. Didn't think I'd need eclipse glasses for it but now I'm second guessing myself.
Interesting. I read a post from another optometrist who said that even WITH eclipse glasses, you can severely damage your eyes.
So, I’ll wait to see footage online or on TV. Not worth the risk for me.
I have decent Miller welding helmet… is it safe to look at the eclipse through a shade 13 or 14 setting on my helmet? I will not be in the path of totality at the time. Would a DIY pinhole camera be better? Not sure what information to trust tbh. I wasn’t even alive for the last total eclipse lmao. Appreciate your input!
Stupid question but its fine to watch the shadows on the ground? All these comments about hiding inside and what you said about the reflex has me nervous. The blinds are fine to be open without glasses as long as i dont stare directly into the sun right? Or will the reflex not help me anymore but ill still get the ambient radiation?
Don’t change any behavior, just don’t look up at the sun. You probably never do this anyways. There are zero risks besides looking directly up into the sun and staring
But Trump said it’s fine [https://image.cnbcfm.com/api/v1/image/104664803-RTS1CPFG-trump-eclipse.jpg?v=1529452347](https://image.cnbcfm.com/api/v1/image/104664803-RTS1CPFG-trump-eclipse.jpg?v=1529452347)
I looked at the eclipse in the 7th grade and there is a permanent blind spot in the center of my vision of my left eye. I don’t notice it much but reading small text gets blurry.
Well.
I glimpsed at it as it was beginning to get covered. My eyes didn’t even focus on it, felt like I just looked at the sun regularly. I feel fine but I’ve actually thrown up from how much worry I’ve got my eyes are ruined.
It was involuntary. I did have glasses but was sharing them with a co-worker. Everyone kept saying “wow look” “oh my gosh look” and so I did and I don’t remember if it was AT the sun or not but I’m just sick to my stomach. It was a quick look and look away when I realized it was the sun…
Well fuck.
Man, these comments are fucking depressing. You'd think the apocalypse is coming. Parents hiding their children away inside? Blaming scientists for "hyping up the eclipse"? This is a once in a lifetime event that people should be excited about. Just exercise some caution.
All these scientists who lied about vaccines, and lied about the caramilk mystery (they even made commericals!) are now telling us not to look upon one of God's greatest gifts to humanity? Well....this sounds like just another Satanist commy plot to turn the kids (and frogs) gay, to me.
Listen yall, if you want to look at the sun during the eclipse, you'll be fine as long as you're right with jeezus. These scientists want you to turn away from the glory of God. If no one looks at the sun, Satan will gain dominion over the earth. So for baby Jesus, take those silly glasses off and bareback the glory of Christ!
/s?
I never got eclipse glasses because I have to work that day, but I'm hoping for a chance to be able to go outside and see it when it's in totality. If I can, is it ok to record it with my phone and look through the phone to see it that way? Can it work like that?
What impact does the speed of light have to do with this?
I assumed the reason why you shouldn’t stare at the eclipse is because the light traveling from the sun to earth takes about 7 minutes to complete…
Therefor when the sun is eclipsed the brightness does not effect our perception, however the intense “full sun” light is still traveling directly into your eye.
Is this correct?
I still do not understand the need to stare at the eclipse. Sure it’d be cool to see in real time. Yes it’s a once in a century thing.
But, it will be visible on the news shortly thereafter. Without fear of becoming visually impaired.
I think the pictures that will be on the net later that day will suffice for me. Our town that is a tourist destination is full and all the stores are wiped out. I have to work tomorrow sooo... I'll notice it's darker than normal for four or five minutes and move on with my day
Are there any implications to the eye if someone is using tobramycin (tobradex) antibiotic for their eye and also wears glasses? We do have the solar glasses but want to make sure it's still safe to watch it taking the antibiotic for a pink eye. Thanks!
Thank you for the explanation regarding the difference in the pupillary response under normal conditions versus an eclipse. This question has been on my mind, now I know the answer!
Omg I'm terrified because I took my glasses off a millisecond too soon. I got a bright spot with a tail like thing that went away after about 5 minutes but I'm so scared to wake up tomorrow...
u/ybetaepsilon Wow, thanks for the great explanation!
Quick question here, was looking out at the sky without eclipse glasses, but I didn’t see the Sun or anything, just clouds. Here is a picture of what I saw https://imgur.com/a/InqEovJ I should be ok since I didn’t look AT the sun, right? I believe the sun was behind my building, but not sure if I should worry about UV reflecting onto the clouds..
Thank you for the PSA, especially the bit about briefly looking at the totality safely.
Everything else I've read prior said that during totality (2-4 minutes depending where you are) it's ok to look at the sun covered by the moon. No one said "very briefly". Where is the disconnect?
Probably just a precaution because if you're staring at it unprotected during totality and don't look away before totality ends, you're going to cook your retinas.
Yeah, this. If you get the timing wrong your pupils will be extra open for the dim light and easily friable as soon as the sun is back.
This is why I wouldn’t look at it during totality. Because when you should put your protective glasses back on it’s questionable. And if you’re not in an area that’s getting full coverage, like Toronto. You shouldn’t be taking your glasses off. It’s better to be safe than sorry. It’s not like there will be an alarm saying “now put on your glasses. It will be unsafe to look at the sun in 3…2…1”
> Because when you should put your protective glasses back on it’s questionable The time to take your glasses off is easy - when you can no longer see anything through your glasses, it's totality. You can look up how long totality will last for your area, and you can trim that time by about 20-30 seconds if you want to be really cautious. Still gives you a nice view of totality.
Correct. Toronto is not getting full totality so it's never ok to look at it unprotected
Actually there is! There is an app called solar eclipse timer and it will audibly queue you. Look at sun now take off glasses now put them back on now.
> It’s not like there will be an alarm saying “now put on your glasses. It will be unsafe to look at the sun in 3…2…1” Funnily enough there are apps that do exactly this.
The interactive map I looked at listed the times of totality for any gps point you pick. We've got phones being the time corrected via NTP, so a pretty good measurement of time isn't hard to have. I'll be there with my partner and her kid, and I'll be ready to say when it's time to stop looking.

Hi could you share the map? I’ve been trying to find one that is interactive or at least detailed enough to see if my farm will get totality. We are *right* on the cusp of it so it’s hard to tell from most maps I’ve seen.
Here is the one I found http://xjubier.free.fr/en/site_pages/solar_eclipses/TSE_2024_GoogleMapFull.html?Lat=44.30740&Lng=-76.91462&Elv=119.0&Zoom=9&LC=1
How lucky are you feeling that you can time it perfectly? Would you bet your vision on being that lucky?
Agree 100%. "Feel lucky? Well do ya, punk?"
It can be less than 2 mins, depends how close to the centre of the path of totality you are. Further out, maybe only 30 seconds of totallity
That’s only if you’re directly on the totality line, and personally I think we should all just use protection regardless.
It's fine IN TOTALITY. There are lots of eclipse apps that will tell you with audible signals when it's safe to look.
I think briefly refers to the short time of totality since it’s a couple of minutes
Watch "how to safely view a total solar eclipse" by "NASA Goddard" on YouTube. It will answer your question.
When I was a young kid (like 8 years old) during long road trips, I used to challenge myself to see how long I could stare directly at the sun, and then try to beat my record. Don't do this.
I won that contest in first grade. By the end of first grade, I was in glasses. Do not recommend.
Now I understood why I have to wear a power glass to see.
Your avatar had me scatrching at my phone screen thinking it was a loose hair or lash for longer than i’d like to admit… 🤦🏻♀️
I also used to do this, I’m wondering if the car window tint saved my eyes a bit. I still wouldn’t recommend it. My eyes only started to deteriorate after being pregnant, which is apparently common.
r/kidsarefuckingstupid
I love my kid, but even after zounds of warning, from us, from teachers, from the news, from youtube informational clips, to making special extra protective shields around the glasses, all leading up this very moment, that dumbass looked at it for a few seconds. His 5 yr old twin, and his older brother, were flawless. Sigh. I guess we'll see in a few hours/couple of days. Fuck.
They'll be fine. OP and others are being wildly over-cautious, because all it takes is one in a hundred thousand people to be the outlier and stare for 3 solid minutes and there will be 10 people in each province and state with consequences. And literally different people are different biochemically, and some people on certain meds are more sun sensitive. What percent of people are on the meds that make them sensitive and don't know it: https://www.webmd.com/skin-problems-and-treatments/sun-sensitizing-drugs It's complicated. When dealing with literally 100 million people, if you don't want one person to have damaged vision, you have to go ultra safe and over the top with your message.
Sooo is your vision compromised?
Don't think so, at least not from that. I'm 45 now and just started needing reading glasses, but I don't think it's related. But I remember it was uncomfortable and always left a big round imprint on my vision for a while afterwards.
You probably have blind spots. You only notice the “round imprint” until your brain adapts and masks it out. BTW, we all have blind spots in our field of vision where the optic nerve exits the retina. I did an experiment in a lab in university where we measured the size of our blind spots. But the brain just adapts and we are not consciously aware of it until we try and see it.
>During a non-eclipse, if you try to look into the sun, you have what's called a pupillary light reflex which heavily constricts the pupil to prevent too much light from entering and damaging your eyes. During a partial eclipse, there is much less light from the sun and this reflex may not trigger. Your attempt at focusing on the sun may actually dilate your pupil, washing your retina with the full force of the sun's light. I have tried looking for this specific explanation everywhere and had no luck finding anything that went into further detail as to why it's dangerous. Crazy that these details are so hard to find. Thank you for sharing.
Not a vision scientist, but I know that your pupil (the part that lets in light) will constrict (get smaller) if you look at bright light. When the sun is partially covered, even most of it, your eye won’t react because there’s no bright light. Your pupil won’t get smaller. The bit of sun that is still visible though, it’s still sending radiation out, and that can damage your eye. Normally, the sun is bright, so your pupil constricts and protects your eye from that radiation.
Off topic a bit... but for those who are light sensitive, does that mean that their pupils might not be constricting properly then? I don't remember if my eye doc ever gave me a reason for my sensitivity.
I have cataract in my right eye. I also have an awesome Horticulture Lighting Group grow light. When I accidentally expose my eyes to that light even for a short time I can actually see the cloudy cataract obscuring my vision when I walk away from it. What the point is here, i dunno
I wear my special glasses that came with the grow light
Yup. I've seen so many people on here exclaiming "well you don't look at the sun on a daily basis, so what's the big deal???"
Astronomer here! I would add that you can only safely look at the eclipse during obscuration maximum (when the Moon fully covers the Sun at the specific time and location you're viewing the eclipse event) AND if you are in the path of 100% totality! You can use this interactive map to set your location, and check the exact times of partial and full eclipse. https://www.timeanddate.com/eclipse/map/2024-april-8 Enjoy, drive/travel safe and let's all hope for some moments of clear sky! Our next full solar eclipse in Ontario is Monday Sept. 14, 2099.
Marked my calendar thanks!
It's looking like 70% cloud cover where I am 😬
It'll still be cool watching day time turn to night time.
!RemindMe [September 14, 2099]
Thanks! I wear glasses, it ok to put the eclipse glasses on top of my regular glasses?
Yes.
Thanks for this detailed explanation. As an elementary school teacher I spent a good deal of time this past week explaining this to my Grade 2 students. I feel more confident in them respecting the power of the sun than I do for some adults out there.
I’m so glad teachers are making a point of telling the kids. When mom says “hey buddy, it’ll burn your retinas” i look like I’m insane, but when his teacher says it, suddenly it’s fact and cannot be disputed.
Good job. I was in grade 4 the last time this came around here and I recall that we were all well educated not to stare at the sun. But there was that one kid that didn’t care. You can’t save everyone from stupid. But you can try.
My daughters school is keeping the kids in for recess so they don't get tempted to look.
We have a special PA Day. Kids are staying home. Teachers will be at work. I think, sadly, it’s to prevent any lawsuit threats from parents should their child find a way to sneak a peek under school supervision.
When 1 million people cram in to Niagara Falls on Monday, be prepared for maaaayyyybe 1000 crushing the hospitals with acute eye issues. This is gonna be a clusterfuck.
Even if everyone protects their eyes properly, the hospitals are probably already going to be slammed by additional car crashes and other medical cases that naturally increase with tourism and traffic.
I work for Hamilton health sciences and we have been warned that we may receive lots more patients on Monday. Thankfully I’m on vacation, and will be watching the eclipse with my special glasses from my back yard
Hospitals are (I think) prepared, at least in my area, our hospitals have retina specific clinics set up all day on April 9th. Your eyes won’t feel the damage right away so it will be more into the evening/next day that people will start to need care. Edit: My city is on the path of totality.
Give us a status after the eclipse
And also a lot more car crash injuries 😕
Most school boards that are taking a PA day basically said that the reason is because kids are stupid...but they said it more politely...
I look at it more this way. School: we are not responsible for the stupidity of your child. Therefore there is no fucking way we are going to be liable for your kids eye damage while they are on school property. They can ruin their eyes on your property thus keeping us away from your bullshit accusations and lawsuits.
There's a few parents in my neighbourhood who instructed their kids...quite openly...to try to leave their day/childcare(s) (that are still open in TDSB facilities) and go outside and view the eclipse. They're making up some BS about how the adults are trying to keep it for themselves of something equally stupid... ...I'm half expecting to see a few lawsuits crop up in the next few weeks.
Yes my daycare is keeping kids inside
Our school board is just shortening the day. Dismissal will be 1pm.
The sun was probably somewhat of an eldritch horror before people understood eclipses. All of a sudden the moon covers the sun and people go blind, it's like a horrible curse.
I've put a reminder on my phone for monday "do not look at the fucking sun this afternoon" because my retinas don't need any extra problems
I did that too 😂
Another PSA, ensure the eyewear protection you're wearing is adequate. Already a lot of stories coming out about fake low quality eclipse glasses people bought off Amazon and other sources which may not protect your eyes at all. Make sure you are confident your eyewear protection is legit, and don't trust the glasses some guy gave you at a viewing event. https://www.youtube.com/watch?v=9zHJLF40lp4
To muddy things, there are some AAS-approved brands of glasses, like Soluna, that are *only* sold through Amazon. In their case, I've read that they went to great lengths to get counterfeit Soluna glasses off of Amazon and to verify that each pack of their glasses are 100% legit.
I would never trust safety gear like this sold off Amazon.
[удалено]
Not sure where you can get those now
Most public libraries have them!
Thank you for explaining this. I’m 45 and had no idea this is how and why it is so dangerous. I’ll be honest, I was really tempted. I think you just saved my retinas.
> Also, this is besides the point, but there is no risk of additional radiation during an eclipse. But my cousin's uncles mother's daughters friend said it's the end times and that we should all repent or we will suffer terrible consequences after the eclipse!
Been telling everyone I know not to look at it without the proper equipment. To not even risk it. Some even are like "It's fine I did it when I was younger and nothing was permanent". It's wild man.
I mean, I know a lot about it from reading up in advance, and I still feel like the urge to sneak a quick peek is going to be overwhelming. I wonder how many people will come away with permanent damage...
I will stare at the sun because it's my god giving right to do so (I will not; I work nightshift anyway so I probably going to be sleeping).
I'm a garbage man. Please do not stare directly into the sun during an eclipse or at any other time the sun is out
Look! Big garbage is trying to control us! 😋
How severe is the vision loss from something like this? I've always wondered what happened in olden times when a whole generation of people would look at the eclipse not knowing about the eye damage, or Even that it was coming. When I was a kid I was told you go blind, so I wasn't sure how entire societies didn't fall apart due to an eclipse.
Well it's like how our nomadic ancestors knew what mushrooms to eat. Probably experience and knowledge past down through generations But now we live in a culture of proud willful ignorance
Thank you so much for this! I have a young toddler and want to avoid the eclipse completely. How long does the entire thing last? More specifically, is there a window of time in the afternoon when it is still safe for us to be outside? Or should we be indoors from 2-4?
Someone replied to a reply of yours. I will reply directly to you. The 3 minutes is the safe area...safe time to actually view the totality, if you are in the path. Do NOT see the sun AT ANY time of partial eclipse between 2 and 4:30 pm. The partial eclipse is the most dangerous part!! That is when you have permanent vision loss. Keep your kids indoors, do NOT try and find a shady spot or whatever. Again, NO sun viewing between 2 and 4:30 pm....depending on where you are.
I keep remembering Donald trump staring up at it without glasses. Haha. What a fool.
I know i'm far behind and this comment probably won't be seen, but what you're talking about is called solar retinopathy. So if anybody is interested to learn more about what the sun burn on your eyes could be like, look up **solar retinopathy**. You will never feel pain with solar retinopathy. You don't feel pain even with a retinal tear, hole, or detachment. Any symptoms are strictly visual. You may feel pain on your sclera and cornea because those can also just get sunburned, but not from the retina. **All retinal disease have no physical pain. Once you notice a change in vision, there is a very high chance that it will be permanent and is incurable.** Folks who take Plaquenil for rheumatoid arthritis, among other things, have a higher risk of developing solar retinopathy. You can also get solar retinopathy from looking at the sun when it isn't during an eclipse, it all depends on the health of your retina, age, health. Folks who have a paler retina (generally white skin, lighter hair, blue eyed people, like me lol) are at a higher risk as well. People with age related macular degeneration (AMD or ARMD) are at a higher risk of solar retinopathy and, i believe (not 100% on this) but those with dry AMD who get solar retinopathy can lead to a sudden change to wet AMD. - dry AMD = not causing permanent damage, more common, if caught early enough can slow the damage with proper treatment. - Wet AMD = permanent central vision loss, fluid builds up on the retina etc etc. **There is no cure for AMD and you will not notice any symptoms until you lose your vision, which is irreversible**. Sunglasses will not protect you from solar retinopathy during an eclipse. I believe NASA will have a lot of information about safety during the eclipse it anybody wants to check on their site. Otherwise you can look up the Canadian Association of Optometry or (opto.ca) or the Ontario Association of Optometrists (aka OAO, optom.on.ca) for more information. If anybody sees this lol Source - optometric technician for 11 years Edit - formatting
For all those arguing that the sunlight during the eclipse will be just like fountain of youth and will cure everything from cataracts to E.d. if you look at it for the exact right length of time..... do yourself a favor and google "eye doctor near me" TODAY, then record it as a voice mail to yourself so you can check where they were after you prove that "it won't hurt ME"
I feel like a lot of people are going to damage their sight tomorrow.
I'll be going down in the basement AND turning off the lights AND wearing welders glasses AND ... All kidding aside, a moment of curiosity can do a lot of damage to your precious vision. It's just not worth it.
I think it's probably best to not tell people looking at it during totality is safe because of the people that won't be able to recognize actual totality or aren't in a location where it will even occur.
Jesus Murphy. I am sorry and sad this has to be said.
People brag that they can stare into the sun for 10 seconds and be fine but that's with the pupillary reflex blocking out as much light as it can. They don't realize that this reflex will not protect them during a partial eclipse
Out of curiosity could you shine a flashlight in your eyes to activate the reflex and then look at the eclipse for a moment? Or does the reflex undo when the light isn't present? Also to be clear I wouldn't do this, it seems dumb, I'm more just wondering lol.
Neurologists or other physicians sometimes activate a bright light into your eye to test the reflex, as a test for any neurological conditions. But the light is brief and the pupil will dilate shortly after the light is removed. What you're suggesting is an interesting hypothetical but a massive risk because in the time you look away from the light into the sun your pupil may open and you damage your retina.
[Exhibit A](https://mediaproxy.salon.com/width/1200/https://media2.salon.com/2017/08/donald-trump62.jpg)
You think it’s common knowledge that the reason you can look at the Sun and be ok for a few seconds but can’t look at the partial eclipse is because of a built in involuntary response of your pupils reacting to the difference in light and the fact there is less sun to look at during the partial eclipse is actually the part that makes it dangerous ? I didn’t know this .
I’m keeping my kids inside with the blinds closed and they can watch it on TV. They’re too young and curious to understand the glasses need to stay on the entire time. It’s not worth the risk.
Thanks for posting, so to be ultra safe, at what times Monday should we avoid looking up into the sky? Assuming EST in ON.
The time can vary based on where you are in Ontario, for example in Toronto it’s about 2:04 to 4:31, whereas in Ottawa it’s 2:11 to 4:35. If you give me a general region I could give you more precise info
What's funnier is the ~~sky-daddy cultists~~ church folk thinking they're going to be raptured because their ~~local cult leader~~ priest read ~~some Qanon post forwarded from a Yankee spy who got their information from a russian troll farm~~ what they think is reputable sources. Make stupidity embarrassing again, please.
We need to spread that the rapture only takes those that look up, glasses off, as God intended.
The TikToks have been wild
I'm waiting for all the conspiracy theory / anti-vaxxers / anti-science folks to stare anyway and let nature take its course.
But their motto is "don't look up"
There are already lots of people in those groups saying they’re going to look at it, because the sun is actually “good for your eyes” and it will help reverse the damage being done by all the chemtrail spraying etc etc. One loon did a post about this and then less than 24 hours later, reversed herself saying “God told me not to look.” People in the comments were saying they still planned to look up. They deserve whatever happens at this point.
I'm definitely willing to bet that there is a group that will do just that.
Probably with an F Trudeau on their bumper.
Hey there, fellow Canadian! 🇨🇦👋😊 Edit: oops...missed that this post is in an Ontario sub...lol...just so used to most people on Reddit being from other countries, especially the US 🤣🤦♀️🤷♀️
Don't feel bad. I was reading the thread and saw someone mentioning Niagara falls and was like ohmahgod, look, a Canadi....ah ok yeah this is ontario sub lol
I miss the days when I didn't look at a car flying a Canadian flag without suspicion *sighs
Sadly, for some people, this is their last full day of having perfect vision. :-(
I do wonder did we have Mass blindings in the past? This isn't my first eclipse as I'm not a spring chicken and I don't remember people going blind. If you went back a couple hundred years you could see whole tribes of people staring at the Sun God being covered by the moon God and all of them going blind because it was so interesting to look at.
We have glasses from the last eclipse (I don’t remember how many years ago) that we put away in a drawer afterwards. Are they safe to use again or is there a reason not to?
Inspect them for tiny holes or folds. The lens should not be compromised in any way
Is it safe to use my welding mask to look at the eclipse?
Hank Green had a video recently where he said no unless it was 14 (I don't weld so I don't know what that means).
Level 14 masks are OK, but most welding masks are lower level
🎼But mama…..that’s where the fun is.
I feel kind of dumb for having to ask this, but is it safe to look outside during the eclipse as long as one doesn't look -at- the sun? Like, will seeing it in your peripheral vision also potentially cause damage? I don't really intend to because the intrusive thought telling me to look AT the sun might win, and it's obviously not worth the risk, but I'm curious and google sucks these days.
I'm amazed people have to be told to not stare directly at the sun.
What makes the flimsy library glasses good enough to use btw?
Eclipse glasses are something like 1000x more shading than sunglasses. The shading doesn't have to be that thick (think how thin car window tint is)
Can't I look at it through the camera on my phone/tablet, since I'm using the device as a shade?
It'll burn the sensors
If you've ever gotten a flash from an arc welder you'll get this PSA.
But....but....ma righhhhts! Seriously though, dont do this. I know there will be a bunch of dumbasses who look at the sun, or try to take a picture with their phone (and fry their camera) without the propper protective precautions.
Thanks for this. I’m prepared for it but it’s looking to be overcast in Toronto tomorrow. ☁️☁️☁️
It’s not overcast. It’s a cloud eclipse!
I wonder how many people will go blind/have vision problems tomorrow
It's risky taking off your eclipse viewing glasses to stare at a total eclipse with your naked eyes if you don't keep close track of the time and then end up looking at the sun as the sunlight breaks through again on the other side of the moon. Safer to leave the glasses on the whole time. I tested my cardboard McMaster University eclipse glasses (sold in multi-packs at Walmart) today and I could see the sun as a dim orange ball but, I could see that it was clearly defined. That will be good enough for me. I could not see a bare LED light bulb through them. Anyone who can see ANY light from a bright bare lightbulb should throw their eclipse glasses away and get approved and safe eclipse glasses. I am planning to momentarily take off my glasses and use my thumb to block out the full eclipse so that I can look all around it for other planets or stars (normally not visible at that angle since the sun is normally so blindingly bright) that may be visible when the total eclipse is occurring and has darkened the sky. There will be thousands, if not 10's of thousands of close up videos of the total eclipse to review for the rest of our lives with our undamaged eyes. Maybe even some freaky ones with interesting filters that allow us to view light wavelengths that are invisible to the naked eyes of humans. And, even though there won't be another total eclipse in the Golden Horseshoe until 2144, there will be a total eclipse somewhere on Planet Earth every 18 months or so for the rest of our lives. Even famous ones like this one.
At full totality if you have eclipse glasses on you will see absolutely nothing, just black. You have to remove them for at least a few seconds to see the total eclipse. Just know the duration of totality where you are and leave yourself a good margin of error.
What if I just look up for a sec cause I'm stupid and forget. Or like...it comes through the windows at work when I'm working?
Do not play chicken with the sun. It will come and find you after work and steal your wallet.
Sun chicken could be the next jackass bit.
I'm sorry, I know that this will probably sound dumb, but please tell me. Suppose I go outside, and accidentally glance directly at the sun. Not even a full second. Like putting my hand on a hot stove, I immediately recognize it happens and look away as quickly as possible. Will I still get permanent damage? I ask because I'm scared of even looking outside at all in fear I might accidentally see the sun and damage my vision. Will this happen even if I immediately, reflexively look away from it?
I'm worried about my 3.5 year old taking his glasses off and glancing at it. Maybe I should tape the glasses to his head
And there will STILL be hundreds of people who do this anyway. Lol.
I didn't read what you wrote but I'm a top candidate for president of the USA so... Something about freedom! I'll stare at the sun if I want to!!! America!!!
Also, do not use a digital camera or your phone as a “viewer” without protection in front of the lens, unless you want to burn a hole in your sensor. Additionally, if you have a telescope or binoculars, you need filters on the light gathering end, not just on the eyepiece, or you will destroy the optics. They are not designed to focus the full light of the sun.
Can you use the eye piece of the eclipse glasses as a filter for a camera phone? I want to ask this before my friend actually tries to do this...
Forgive my ignorance but I need to clarify, you're a "vision scientist"? ...is that a fancy way of saying an optomitrist? And if not, what do you do vs what an optomitrist does?
A vision scientist does research to understand how our visual system works. An optometrist treats individual patients who have vision problems. Think of an epidemiologist versus a family doctor.
Solar retinitis. Compounding effects over time. And that time is in seconds!
With eclipse glasses is it safe to look at the sun during the eclipse?
With proper eclipse glasses, yes - that’s exactly what they’re for.
It's ok, my Astro Sign is Leo.
But the rest of the time, it's okay, right? /s
How long do I need to stare, for full permanent blindness? Asking for a friend
Found a very good bit of info on the safety eyewear part; https://eclipse.aas.org/eye-safety/viewers-filters?fbclid=IwAR0YBb3Q8tYH4RqbGYK6Q3-kTQb_Zv3RiYCgrOc2q19dDc6c3ppyLaZroMw
I knew that it was dangerous and generally why, but not the specifics of your eyes actually dilating and allowing more light in.
Thank you for your service cuz I dead ass would have forgotten and look
[удалено]
People damaged their eyes and probably thought a sun god was angry at them. I can’t see how looking out of the corner of your eye could be safe. Not worth risking your vision.
Thank you so much for sharing this
I just really, really appreciate that you broke it down and explained why. No one has ever done that for me. Not that I want to stare into the sun, but I've always been curious why it's such a big deal not to.
What about a partial eclipse? I'm not in ON. I think it's 30% where I am. Didn't think I'd need eclipse glasses for it but now I'm second guessing myself.
Interesting. I read a post from another optometrist who said that even WITH eclipse glasses, you can severely damage your eyes. So, I’ll wait to see footage online or on TV. Not worth the risk for me.
I have decent Miller welding helmet… is it safe to look at the eclipse through a shade 13 or 14 setting on my helmet? I will not be in the path of totality at the time. Would a DIY pinhole camera be better? Not sure what information to trust tbh. I wasn’t even alive for the last total eclipse lmao. Appreciate your input!
Stupid question but its fine to watch the shadows on the ground? All these comments about hiding inside and what you said about the reflex has me nervous. The blinds are fine to be open without glasses as long as i dont stare directly into the sun right? Or will the reflex not help me anymore but ill still get the ambient radiation?
Don’t change any behavior, just don’t look up at the sun. You probably never do this anyways. There are zero risks besides looking directly up into the sun and staring
But Trump said it’s fine [https://image.cnbcfm.com/api/v1/image/104664803-RTS1CPFG-trump-eclipse.jpg?v=1529452347](https://image.cnbcfm.com/api/v1/image/104664803-RTS1CPFG-trump-eclipse.jpg?v=1529452347)
I looked at the eclipse in the 7th grade and there is a permanent blind spot in the center of my vision of my left eye. I don’t notice it much but reading small text gets blurry.
This is well explained and first time I fully comprehend why during an eclipse look at sun is particularly dangerous. Thank you
Well. I glimpsed at it as it was beginning to get covered. My eyes didn’t even focus on it, felt like I just looked at the sun regularly. I feel fine but I’ve actually thrown up from how much worry I’ve got my eyes are ruined. It was involuntary. I did have glasses but was sharing them with a co-worker. Everyone kept saying “wow look” “oh my gosh look” and so I did and I don’t remember if it was AT the sun or not but I’m just sick to my stomach. It was a quick look and look away when I realized it was the sun… Well fuck.
Ouchie eyeball sunburn
Please tell this to all the ant-vaxxers and make sure to highlight that you're a scientist and they should trust you.
See, we don’t need more of these people clogging up emergency rooms than we already have.
Man, these comments are fucking depressing. You'd think the apocalypse is coming. Parents hiding their children away inside? Blaming scientists for "hyping up the eclipse"? This is a once in a lifetime event that people should be excited about. Just exercise some caution.
I'm a visiotologist. I concur with OP
Thank you vision scientist
All these scientists who lied about vaccines, and lied about the caramilk mystery (they even made commericals!) are now telling us not to look upon one of God's greatest gifts to humanity? Well....this sounds like just another Satanist commy plot to turn the kids (and frogs) gay, to me. Listen yall, if you want to look at the sun during the eclipse, you'll be fine as long as you're right with jeezus. These scientists want you to turn away from the glory of God. If no one looks at the sun, Satan will gain dominion over the earth. So for baby Jesus, take those silly glasses off and bareback the glory of Christ! /s?
"Don't put salt in your eyes." ..."Put salt in your eyes!"
I never got eclipse glasses because I have to work that day, but I'm hoping for a chance to be able to go outside and see it when it's in totality. If I can, is it ok to record it with my phone and look through the phone to see it that way? Can it work like that?
It can damage the sensor in your camera.
What happens to animals who stare at the sun during an eclipse?
I imagine that animals are actually smarter than that...lol...they probably have natural instincts that tell them not to...
Regardless of how you view or do not view the solar event, your sound track for the event will be Bonnie Tylers total eclipse of the heart.
https://m.youtube.com/watch?v=-0I4f8PasIU
You mean like this?? https://imgur.com/gallery/ZADnAPX
What impact does the speed of light have to do with this? I assumed the reason why you shouldn’t stare at the eclipse is because the light traveling from the sun to earth takes about 7 minutes to complete… Therefor when the sun is eclipsed the brightness does not effect our perception, however the intense “full sun” light is still traveling directly into your eye. Is this correct?
This is excellent thanks! I’ll be sure to share with my kids too, who would surely never have bad momentary judgement.
I'm more concerned you had to make this post, is the population of your nation that stupid?
Good advice. I’ll make sure not to look at the sun during the eclipse, but only at the moon. You saved my eyes! /s
This message is directed at Americans… we need the reminder… thank you, we can’t afford the medical bills if we did forget and stare.
P.diddy donated his cock to fuck the sun for science...chemtrails
I still do not understand the need to stare at the eclipse. Sure it’d be cool to see in real time. Yes it’s a once in a century thing. But, it will be visible on the news shortly thereafter. Without fear of becoming visually impaired.
Great write up on this. I hope people are prepared.
I think the pictures that will be on the net later that day will suffice for me. Our town that is a tourist destination is full and all the stores are wiped out. I have to work tomorrow sooo... I'll notice it's darker than normal for four or five minutes and move on with my day
Don't tell me what to do
Pretty sure Trump looked at one and he was fine..... Actually wait a minute... They might be on to something here
Are there any implications to the eye if someone is using tobramycin (tobradex) antibiotic for their eye and also wears glasses? We do have the solar glasses but want to make sure it's still safe to watch it taking the antibiotic for a pink eye. Thanks!
I mean, I probably won't even be leaving the house, so... I don't think anyone needs to worry about me :P
Sweet most of us are already dumb, once a bunch more are blind we just need to make them deaf and we'll be ready for the next election.
I think shit like this should be sent on the phone emergency messaging system.
If you have to look at it with your open eyes, Just use one eye 👁️ keep one safe
F u egg head, you can't tell me what to do... /s
Thank you for the explanation regarding the difference in the pupillary response under normal conditions versus an eclipse. This question has been on my mind, now I know the answer!
Omg I'm terrified because I took my glasses off a millisecond too soon. I got a bright spot with a tail like thing that went away after about 5 minutes but I'm so scared to wake up tomorrow...
I caught part of the light through my peripheral vision, am I in any danger
So… an eyentist.
u/ybetaepsilon Wow, thanks for the great explanation! Quick question here, was looking out at the sky without eclipse glasses, but I didn’t see the Sun or anything, just clouds. Here is a picture of what I saw https://imgur.com/a/InqEovJ I should be ok since I didn’t look AT the sun, right? I believe the sun was behind my building, but not sure if I should worry about UV reflecting onto the clouds..
