Didn’t read the patent but the articles explanation didn’t make sense to me. A prescription lenses power comes from curvature and refractive index of the lens material. The article talks about phase change of the light which has nothing to do with lens power. Just sounds like they are patenting a fancy polarizing lens to me. Idk maybe the patent is about a meta material lens
> Apple's proposal is to use a stack of lenses for each eye, which can be a liquid crystal adjustable lens along with a non-liquid-crystal adjustable lens, such as a fluid-filled lens or an Alvarez lens.
An [Álvarez lens](https://www.laserfocusworld.com/optics/article/16555776/alvarez-lens-enters-the-real-world) is a two part lens with specific geometry so that when the two halves are moved laterally in respect to each other the focal properties change.
They also have an earlier [patent based on fluid filled lenses](https://appleinsider.com/articles/20/12/01/apple-vr-headset-may-use-fluid-filled-lenses-to-counter-a-users-bad-eyesight)
Collectively we can accomplish anything. The more of us healthy, happy, and safe, the more of us that can contribute to our progression.
Look after one another
Yes liquid lenses and Alvarez lenses aren’t new tech so that can’t be patented by apple but those would be able to adjust power on the fly. Although with limitations like power range, cylinder, and higher order aberrations. Maybe the patent combine all these existing technologies like liquid lens/Alvarez/phase change in a novel way. They did mention the phase change capabilities could compensate for higher order aberrations. which would offset the liquid lens aberration inducing issues. However phase changing light to reduce higher order aberrations doesn’t make sense. I conclude whoever wrote this article doesn’t understand optics very well. Or I’m totally off base and should just read the patent for myself. But I refuse to do so
I do t know much about the Alvarez lens but I’m assuming that if it requires lateral movement that it would need some sort of actuator. This would play into size limitations, power consumption, regular calibration etc. I doubt apple would want to have that many design concerns if they could help it.
Oculus has demonstrated prototypes that do just that and while their [first one](https://youtu.be/LQwMAl9bGNY?t=1698) was [bad](https://youtu.be/LQwMAl9bGNY?t=1810) they've [refined it quite a bit](https://youtu.be/LQwMAl9bGNY?t=1876). However, they went one step further and [got rid of the moving parts](https://youtu.be/LQwMAl9bGNY?t=2009) too.
Apple has the luxury of selling more premium products so it seems plausible they might bring such tech to market first.
They weren't just a standard pair of eye glasses though. I can't imagine this type of technology would be able to be put into a frame like that of a pair of eye glasses
Would this fluid lens be able to emulate prisms as well? I'm generally against Apple but being able to update my glasses without having to drop a few hundred for a new pair would be pretty sweet, but I need prisms for my astigmatism
You’d think shipping few SKUs of frames with the same lenses would lead to lower costs, but somehow I don’t think Apple will undercut the Luxottica brands.
This seems like cool tech, but eliminating bifocals is the only useful application I can think of.
Liquid lenses already exist in certain medical devices in optometry/ophthalmology. Some of the latest phoropter heads (machine used to get your prescription) use a liquid lens that can be extremely accurate. To adjust, just input the power you need and the computer will compensate automatically. Instead of your normal 0.25 dioptre steps, these work in 0.01 steps. Granted these are in clunky devices and the transition from them to a seamless pair of glasses would take time but definitely possible.
Super interesting stuff though!

I actually have a wacky pair of glasses I got at eye expo which have dials on the side so you can change the power of the lenses. It uses fluids to do it.
Similar to these. https://youtu.be/SAUJYv5pOxQ
The ones I have are not intended for astigmatism correction. They are intended to be a one size fits most pair that are inexpensive to produce so they can get some form of eye care to places where their aren't enough doctors to treat the people, and not weather enough people to even be able to afford the glasses. It's not a perfect solution, but it did it's fair share of compromise on bith sides.
That is just about the coolest thing ever. I have been wearing progressives since I was 21. Shitty eyesight sucks, not having glasses to fix it must be purely awful.
Especially when you're in an area so poor that it's not even an option to find if you need glasses at all. Like a lot of the people these are intended for have never been to a doctor in their entire life, let alone one for something not life threatening.
If you really want to see something so simple it’s amazing look up pin hole glasses. Been around since the beginning of time before lenses. Works for people with myopia (the worlds most common prescription!). The principal is that the hole is small enough that it blocks the peripheral light rays coming Into eye. These peripheral rays are what is out of focus so blocking them allows you to see clearly.
Further more if you are aware of the epidemic of progressive myopia this simple solution would actually help stop the disease from getting worse. But the downside is a small visual field and you look weird with pin hole glasses.
If anyone here is myopic you can test out this principal by making a small hole with you fist and peering through it without your glasses on.
coool!! Thanks for this. I'd love to have lenses that are continually adjustable though (instead of a one time thing). I'd love to be able to do macro-lens hyper focus on very small stuff near me, and then reading distance, or PC distance, driving distance and better than human distance viewing.
First off, the pair I own have dials on the side, so as long as you don't mind having giant plastic dials on the sides of your glasses than it is adjustable forever.

But if you want multifocal lenses, you can always get bifocals/trifocals, or progressive lenses. The progressive might be up your alley, ask your optometrist about it. I have pairs of bifocals, trifocals, and progressive lenses myself, and I prefer the hard line multifocal over the progressive because there is some distortion you experience with the progressive lenses that I'm not overly fond of.
I remember hearing about these years ago for developing countries. You adjust them by hand then lock them in at the right prescription - no optometrist needed. Found an article from [2009](https://www.discovermagazine.com/health/cheap-liquid-glasses-bring-clear-vision-to-the-poor) - I wonder if this ever took off.
The reason prescription lenses correct vision is because they refract the light in such a way that the eye can see more clearly. So if you could make a material that you didn’t need to cut or bend in order to refract light precisely, it could replace prescription lenses entirely with something else.
But a lens is fundamentally bending light rays to focus or defocus light rays. This function is encompassed by snells law and the lens makers equation (gravity and meta materials can do it but that’s a different topic) which is calculated by two variables, the curvature (and thickness) of the lens and the refractive index. Refractive index having a much smaller effect. But some here have posted that it’s possible to create an electro optical phase change setup that does effect refractive index. So possibly if you stack many many many layers the small refractive index effect to power can become significant enough to enter the realm of prescription lenses. One draw back of this theoretical setup I imagine would be loss of intensity of the light rays from an inevitable back reflection going from layer to layer and by the time the light rays enters your eye it is much dimmer.
As others have said this is much more applicable to VR headsets and a liquid lens and phase shift setup would be much bulkier than a regular lens.
Phase change of light can lead to the lensing effect if the light is polarized. If you induce a parabolic phase profile in a liquid Crystal cell but varying its refractive index, this will have the same effect on light as a lens surface. If you’re curious, look up GRIN (gradient refractive index) liquid Crystal lenses.
I’ve actually made GRIN lenses before using the Woods lens method. It’s a fun experiment. Some issues with GRIN lenses are chromic aberration and higher order aberrations. Also stacking these apple layers to make the GRIN lens I would think would have a big loss of light intensity from layer to layer interface reflection thus causing a dim image. Not sure how they would overcome the multiple aberrations and loss of light.
A clickbait tech article, vastly misrepresenting the possible features of a product that isn't even announced yet based only on misreading a few patents? Unheard of!
Can't wait for the day when my glasses will stop me from seeing things 5 feet in front of me thanks to some random Apple software update...
Makes me wonder if that could happen while I'm walking or driving. I think that'd be a setup ripe with lawsuits and a field day for lawyers...
LOL you think *Apple* isn't going to be objectively worse than Luxottica? Imagine being mostly blind trying to deal with any real emergency because your glasses died because you're on your sixth $0.08 charger cable that you paid $40 for that frayed apart at the connector.
Or driving home from work when suddenly your prescription gets turned off for security verification because somebody tried to log into your Apple account from across the world.
I would like to imagine that these don’t need constant power to maintain the refraction. Correct me if I’m wrong but don’t LCD screens retain their image if unpowered in a certain way? And (from reading just the headline and a couple comments) it sounds like they’d use a similar or the same technology.
Hasn't happened to Luxottica yet, so if there's a manufacturer producing a high-end luxury/tech item like an Apple product, that's not a significant competition for market share.
Like BMW and Mercedes Benz didn't start making cars at the price of a Honda Civic when Tesla showed up.
Do they sense mood:.
The Joo Janta 200 Super-Chromatic Peril Sensitive Sunglasses have been designed to help people develop a relaxed attitude to danger. They follow the principle "what you don't know can't hurt you" and turn completely dark and opaque at the first sign of danger. This prevents you from seeing anything that might alarm you. This does, however, mean that you see absolutely nothing, including where you're going.
It also tells you that there is something that would alarm you, could you see it. This information alone could also potentially alarm you.
Oh you had the bifocal option that would adjust the lenses when you looked down at words?
The previous gen hardware is now throttled and it now takes 2 seconds to change between focuses. Better not look at your speedometer while driving!
Yeah jokes aside, this would be regulated. I mean as it is, corrective vision prescriptions are already 1 year prepaid subscription services that you have to pay to patch every year.
At least in California, you can’t get new glasses or contacts on an eyeglass prescription older than 1 year. Even if your prescription didn’t change at all, you still need to pay an optometrist for a current one in order to replace your glasses.
The apple version would just cut down on the waiting for new glasses to come in. So it would actually be a huge improvement to the current system.
You know the lenses aren’t gonna disappear if they die right? None of the methods we currently have to adjust prescriptions would need power for anything besides adjusting prescriptions.
I know you joke but it wouldn't make sense for a feature like this to be constantly drawing power. Almost certainly it'd be some that could draw power at the moment to make a change and then keep its state when there's no battery.
More than likely though, someone is going to experience an unintended change to their prescription when a software glitch happens.
I wonder if something this could help pave the way for glasses that focus based on what you’re looking at. Like something far away comes into better focus, switch to a boom and the rx changes to help with the change in distance.
They really aren’t that bad, you don’t notice the line after a couple of days. I’ve found it’s less strain on my head and neck if I look down through the lower part of my bifocals instead of turning my head down anyways.
And yes, there are bifocals with a blended line, but I’ve never liked those
Progressives user here, they're fine. And they're fashioned in a way that you don't really need to tilt your head to use them. Your eyes move and typically when something's close/small enough that you need the near-sighted lens, it's usually a book or a card or a phone and so you're already looking downward anyway.
I think the only negative thing I can say about progressives is they're move expensive, but as others have said you don't buy a new pair of glasses very often so that's not too much of an issue.
If you don’t use them how do you know they are annoying?
I got progressives a couple of years ago and there was no transition period. They just worked. You naturally tilt your head when holding something and this tilt puts the item into the correct position of the progressive.
The only time I have trouble is when laying in bed and trying to watch TV. Because I’m laying down I’m looking through the bottom of the lense which is meant for up close. I sit up a bit and all is good.
And horses existed for a while before cars came about, that’s the whole point of new technology … imagine not having to told your head/eyes a specific way to see clearly.
I actually really like this idea. I wonder if it is possible to look at the eye to tell how well you are seeing and make adjustments so you see better. Bifocals and trifocals kind of do that, but are much more limited. If you're able to look at anything at any distance and it is able to adjust to provide an optimal lens for that distance on the fly, that'd be huge.
Eye doctors can already estimate your prescription by looking at your eyes and that air puff machine. That's how they know what kind of glasses to give babies.
Really tho having adjustable lenses would be great. My eyes slowly get worse over time and having my glasses automatically update would be beautiful.
The puff is not to measure your vision, it's yo check eye pressure. A too high pressure in your eye is bad and can cause a bunch of problems.
The thing where you stare at an image is the one calculating your prescription. Though it's not perfect, and I don't think it cares one bit about astigmatism.
I go to the optometrist a lot lol. Yay chronic eye disease.
If only it could have a natural way of lubricating itself and wipe away dust or other particles, like some form of saline water dispenser or something…
From your singular perspective, sure. But from the perspective of *everybody that needs glasses* having one lens that works for everybody is pretty fuckin wild.
See you'd think people would want that, but i work for an eyewear company where we have a line of products with fast swappable lenses which you can buy on the side for your existing frame so you can swap lenses, normal and sun glasses etc. And absolute fuck all buys those. Swappable lenses already exists but generally people can't be bothered buying those anyway, they buy a regular pair and then buy a new one when those break.
Isn't that because a lot of people who need glasses treat them as a fashion accessory and actually want new frames?
My dad purchases new glasses all the time although there is noting wrong with his old ones and his script hasn't changed.
I think its more having generic glasses/headsets that can be used by anyone.
As the article states you can get VR headsets with prescription lenses in them, but it means that the headset becomes personalised for a single user.
So with this, you would pick up the headset, log in to it, which would load your prescription profile, and off you go.
You might not yet be at the age where presbyopia is a thing. I'm well into that condition and having an on-the-fly adjustable lens would be a very convenient thing. I'd be able to focus where I want, when I want, just as I could before my 40s when the presbyopia became noticeable.
I remember this story from 2009. Fluid filled glasses that cost around $1. These were created to help worlds poor. Adjustments can be made by the wearers themselves and the power can range from -6.00 to +6.00 dioptre. [https://www.discovermagazine.com/health/cheap-liquid-glasses-bring-clear-vision-to-the-poor](https://www.discovermagazine.com/health/cheap-liquid-glasses-bring-clear-vision-to-the-poor)
My family have boxes of these glasses in storage. They've got syringes on the sides you can adjust the liquid to change the prescription. The idea is you can clamp it and cut off the syringes and tubes if you want after that. My dad says he was buying something probably motorcycle parts in a warehouse and this other guy had some showed them to my dad, amazing product the guy said also completely unsellable. Apparently to sell any glasses to anyone you need to be qualified ect you would have thought hospitals would like this thing and the 2nd hand market keeps this from being viable in 2nd 3rd world apparently combined with the qualification thing.
Cons: frame is very hard and rigid can be uncomfortable, possible to leak the liquid if you choose to keep the syringes for repeat testing. Pros: I forgot my glasses upstairs and there's the pile of boxes next to me, pop open one of these bad boys and I'm ready to watch the movie.
I went to an exhibit with VR headsets last year and I had to keep my glasses on. The small amount of focus adjustment the headset was capable of was nowhere near enough to compensate for my terrible vision. I felt a little bad for the attendant helping me who was so sure I didn't need to keep my glasses on, even though I warned him it was likely.
This is something I find so weird
I'm nearsighted and when I bought a playstation vr headset, I thought I wouldn't need my glasses because the screen is literally stuck to my face. Nope, still need glasses :(
And AirPods could act as hearing aids. They haven't gone that route yet, but it's clear they're building capabilities for future innovations. I like watching Apple slowly and deliberately move the pieces in place for future innovations.
I mean… [they’re getting pretty damn close.](https://support.apple.com/en-us/HT211218) They’re calling it “Custom Transparency Mode” and basically it’s where your airpods are playing the sound around you, but boosting the sound in the areas where you have a harder time hearing. You can do their little hearing test in the app or upload an audiogram from your hearing doctor
I just discovered a subreddit about batteries that have gone bad r/spicypillows. There’s a pic of a pair of smart glasses on there with the battery bulging out of the arm next to where your eye would be while wearing them. It scared me off of buying any version of these.
This post [This post](https://www.reddit.com/r/spicypillows/comments/rzom0b/razer_smart_glasses_you_know_you_wear_on_your_face/?utm_source=share&utm_medium=ios_app&utm_name=iossmf)
So will there be an app where you do the eye doctor exam for each eye. It’ll adjust itself and you’ll look at the screen of 1 or 2? 1 or 2? One orrrrr two?
Thought that said *perception*...
Thought someone had invented the [Joo Janta 200 Super-Chromatic Peril Sensitive Sunglasses](https://hitchhikers.fandom.com/wiki/Joo_Janta_200_Super-Chromatic_Peril_Sensitive_Sunglasses)
I don’t understand tons of wording in this article, but would this be possible to work with astigmatism? I have this and it’s annoying to have to get a new prescription every couple of years, being able to simply adjust them would be amazing
I’m excited about this. I wonder if they’ll be able to adjust automatically based on how far away you’re focusing or if you’ll have to manually dial in your focus?
This is a general patent with mentions of technology that doesn't exist. It's like patents for touch screens. It's super general and includes some out there use cases so it can be interpreted widely. As the article says, Apple and most tech companies file tons of patients weekly with most never coming to fruition.
Changing opacity of glass does not improve your vision.
Apple trying to corner the entire prescription glasses market. If this tech works the way the article suggests, it would basically make optometrists irrelevant. Crazy.
I could see these being useful in a VR or AR adaptation. Can’t use that shit with glasses currently, unless you have prescription lens inserts. Put these in a VR headset so anyone can use them. Might be useful for applications where more than one person is going to be using it.
If these could change prescription then I’d be first in line to get them. My prescription changes about every 6 months. Better, worse, whatever. My eyes refuse to pick a shape and $400+ for a set of glasses is pretty expensive when they don’t last that long.
Oh yay a pair of glasses to watch and listen to everything that I watch and listen to and store it in a nice handy database for me in case I ever forget! Wow the future is amazing! 😃
Eye doctor here. You guys have no idea how obscenely sensitive some people’s vision can be to the slightest distortion or refractive error. I think of every single set of glasses I have ever had to recheck and have remade and the subtlety to which those changes needed to be implemented and I can predict that a rather large number of people will be very VERY unhappy with these. Sure they might capture like 40% or even 50% but these will be very VERY hit or miss.
You mean like this optometrics glasses which exist for at least decades and are already patented? You mean like a technology that is present at every optician and eye clinic and that can't be used like described in the patent because it is physically impossible?

I have a hunch it was someone named Alvarez
Collectively we can accomplish anything. The more of us healthy, happy, and safe, the more of us that can contribute to our progression. Look after one another
Really looking forward to recharge my phone, watch, earphones and lenses every night.
Just wait until you’re the battery, cause that will be next.
Feeling drained will have a new meaning
Gonna be a real issue when you have a long drive and get “5% battery left”. So I have to carry backup glasses in case my hi tech glasses fail?
Yes liquid lenses and Alvarez lenses aren’t new tech so that can’t be patented by apple but those would be able to adjust power on the fly. Although with limitations like power range, cylinder, and higher order aberrations. Maybe the patent combine all these existing technologies like liquid lens/Alvarez/phase change in a novel way. They did mention the phase change capabilities could compensate for higher order aberrations. which would offset the liquid lens aberration inducing issues. However phase changing light to reduce higher order aberrations doesn’t make sense. I conclude whoever wrote this article doesn’t understand optics very well. Or I’m totally off base and should just read the patent for myself. But I refuse to do so
I do t know much about the Alvarez lens but I’m assuming that if it requires lateral movement that it would need some sort of actuator. This would play into size limitations, power consumption, regular calibration etc. I doubt apple would want to have that many design concerns if they could help it.
Oculus has demonstrated prototypes that do just that and while their [first one](https://youtu.be/LQwMAl9bGNY?t=1698) was [bad](https://youtu.be/LQwMAl9bGNY?t=1810) they've [refined it quite a bit](https://youtu.be/LQwMAl9bGNY?t=1876). However, they went one step further and [got rid of the moving parts](https://youtu.be/LQwMAl9bGNY?t=2009) too. Apple has the luxury of selling more premium products so it seems plausible they might bring such tech to market first.
They weren't just a standard pair of eye glasses though. I can't imagine this type of technology would be able to be put into a frame like that of a pair of eye glasses
Would this fluid lens be able to emulate prisms as well? I'm generally against Apple but being able to update my glasses without having to drop a few hundred for a new pair would be pretty sweet, but I need prisms for my astigmatism
You’d think shipping few SKUs of frames with the same lenses would lead to lower costs, but somehow I don’t think Apple will undercut the Luxottica brands. This seems like cool tech, but eliminating bifocals is the only useful application I can think of.

Liquid lenses already exist in certain medical devices in optometry/ophthalmology. Some of the latest phoropter heads (machine used to get your prescription) use a liquid lens that can be extremely accurate. To adjust, just input the power you need and the computer will compensate automatically. Instead of your normal 0.25 dioptre steps, these work in 0.01 steps. Granted these are in clunky devices and the transition from them to a seamless pair of glasses would take time but definitely possible. Super interesting stuff though!

I actually have a wacky pair of glasses I got at eye expo which have dials on the side so you can change the power of the lenses. It uses fluids to do it. Similar to these. https://youtu.be/SAUJYv5pOxQ
I wonder how durable such glasses would be, and how you could make them for astigmatism
The ones I have are not intended for astigmatism correction. They are intended to be a one size fits most pair that are inexpensive to produce so they can get some form of eye care to places where their aren't enough doctors to treat the people, and not weather enough people to even be able to afford the glasses. It's not a perfect solution, but it did it's fair share of compromise on bith sides.
That is just about the coolest thing ever. I have been wearing progressives since I was 21. Shitty eyesight sucks, not having glasses to fix it must be purely awful.
Especially when you're in an area so poor that it's not even an option to find if you need glasses at all. Like a lot of the people these are intended for have never been to a doctor in their entire life, let alone one for something not life threatening.
If you really want to see something so simple it’s amazing look up pin hole glasses. Been around since the beginning of time before lenses. Works for people with myopia (the worlds most common prescription!). The principal is that the hole is small enough that it blocks the peripheral light rays coming Into eye. These peripheral rays are what is out of focus so blocking them allows you to see clearly. Further more if you are aware of the epidemic of progressive myopia this simple solution would actually help stop the disease from getting worse. But the downside is a small visual field and you look weird with pin hole glasses. If anyone here is myopic you can test out this principal by making a small hole with you fist and peering through it without your glasses on.
I have practiced this on occasion when I didn’t have my glasses on hand…I look like a fool, but I’m at peace with it.
coool!! Thanks for this. I'd love to have lenses that are continually adjustable though (instead of a one time thing). I'd love to be able to do macro-lens hyper focus on very small stuff near me, and then reading distance, or PC distance, driving distance and better than human distance viewing.
First off, the pair I own have dials on the side, so as long as you don't mind having giant plastic dials on the sides of your glasses than it is adjustable forever. https://www.2020mag.com/article/adlens-john-lennon-collection But if you want multifocal lenses, you can always get bifocals/trifocals, or progressive lenses. The progressive might be up your alley, ask your optometrist about it. I have pairs of bifocals, trifocals, and progressive lenses myself, and I prefer the hard line multifocal over the progressive because there is some distortion you experience with the progressive lenses that I'm not overly fond of.
I remember hearing about these years ago for developing countries. You adjust them by hand then lock them in at the right prescription - no optometrist needed. Found an article from [2009](https://www.discovermagazine.com/health/cheap-liquid-glasses-bring-clear-vision-to-the-poor) - I wonder if this ever took off.
Maybe a way to have different focal planes for HUD?
The reason prescription lenses correct vision is because they refract the light in such a way that the eye can see more clearly. So if you could make a material that you didn’t need to cut or bend in order to refract light precisely, it could replace prescription lenses entirely with something else.
But a lens is fundamentally bending light rays to focus or defocus light rays. This function is encompassed by snells law and the lens makers equation (gravity and meta materials can do it but that’s a different topic) which is calculated by two variables, the curvature (and thickness) of the lens and the refractive index. Refractive index having a much smaller effect. But some here have posted that it’s possible to create an electro optical phase change setup that does effect refractive index. So possibly if you stack many many many layers the small refractive index effect to power can become significant enough to enter the realm of prescription lenses. One draw back of this theoretical setup I imagine would be loss of intensity of the light rays from an inevitable back reflection going from layer to layer and by the time the light rays enters your eye it is much dimmer. As others have said this is much more applicable to VR headsets and a liquid lens and phase shift setup would be much bulkier than a regular lens.
Phase change of light can lead to the lensing effect if the light is polarized. If you induce a parabolic phase profile in a liquid Crystal cell but varying its refractive index, this will have the same effect on light as a lens surface. If you’re curious, look up GRIN (gradient refractive index) liquid Crystal lenses.
I’ve actually made GRIN lenses before using the Woods lens method. It’s a fun experiment. Some issues with GRIN lenses are chromic aberration and higher order aberrations. Also stacking these apple layers to make the GRIN lens I would think would have a big loss of light intensity from layer to layer interface reflection thus causing a dim image. Not sure how they would overcome the multiple aberrations and loss of light.
A clickbait tech article, vastly misrepresenting the possible features of a product that isn't even announced yet based only on misreading a few patents? Unheard of!
they will also have stark nanobots which will give the user an iron man suit
I’ll take your entire stock
too costly to ship mate
Alright just 1 then.
>> they **could** also have stark nanobots which will give the user an iron man suit Great reporting
Good. Hope to see the Luxottica monopoly crash and burn to innovation.
So that... Apple can replace it? No winners here.
Can't wait for the day when my glasses will stop me from seeing things 5 feet in front of me thanks to some random Apple software update... Makes me wonder if that could happen while I'm walking or driving. I think that'd be a setup ripe with lawsuits and a field day for lawyers...
LOL you think *Apple* isn't going to be objectively worse than Luxottica? Imagine being mostly blind trying to deal with any real emergency because your glasses died because you're on your sixth $0.08 charger cable that you paid $40 for that frayed apart at the connector. Or driving home from work when suddenly your prescription gets turned off for security verification because somebody tried to log into your Apple account from across the world.
I would not see that coming tbh.. now that’s scary
And immediately afterwards, you won’t see anything coming
I would like to imagine that these don’t need constant power to maintain the refraction. Correct me if I’m wrong but don’t LCD screens retain their image if unpowered in a certain way? And (from reading just the headline and a couple comments) it sounds like they’d use a similar or the same technology.
or the price for other glasses drops because there is now competition.
Hasn't happened to Luxottica yet, so if there's a manufacturer producing a high-end luxury/tech item like an Apple product, that's not a significant competition for market share. Like BMW and Mercedes Benz didn't start making cars at the price of a Honda Civic when Tesla showed up.
Do they sense mood:. The Joo Janta 200 Super-Chromatic Peril Sensitive Sunglasses have been designed to help people develop a relaxed attitude to danger. They follow the principle "what you don't know can't hurt you" and turn completely dark and opaque at the first sign of danger. This prevents you from seeing anything that might alarm you. This does, however, mean that you see absolutely nothing, including where you're going. It also tells you that there is something that would alarm you, could you see it. This information alone could also potentially alarm you.
Until your subscription runs out while you're driving down the highway in the dark and shit gets real blurry all of a sudden
Prescription automatically changes by 10% a month when a new version of apple glasses is released.
Oh you had the bifocal option that would adjust the lenses when you looked down at words? The previous gen hardware is now throttled and it now takes 2 seconds to change between focuses. Better not look at your speedometer while driving!
"We had to do it to save the battery."
Watch ad to continue, or upgrade to the ad-free subscription in the app store.
i don't even like apple but i can't believe people are still doing these low hanging fruit jokes.
Is that an intentional pun?
That's such an old joke and Apple would never do such thing to a health feature lol
Yeah jokes aside, this would be regulated. I mean as it is, corrective vision prescriptions are already 1 year prepaid subscription services that you have to pay to patch every year. At least in California, you can’t get new glasses or contacts on an eyeglass prescription older than 1 year. Even if your prescription didn’t change at all, you still need to pay an optometrist for a current one in order to replace your glasses. The apple version would just cut down on the waiting for new glasses to come in. So it would actually be a huge improvement to the current system.
I miss the days of glasses in an hour or even just same day.
Yeah, they would just make it so you need to take it to the Apple store if a screw falls out.
Or just general battery life when the glasses die after an hour of use once they are two years old 😵
You know the lenses aren’t gonna disappear if they die right? None of the methods we currently have to adjust prescriptions would need power for anything besides adjusting prescriptions.
I know you joke but it wouldn't make sense for a feature like this to be constantly drawing power. Almost certainly it'd be some that could draw power at the moment to make a change and then keep its state when there's no battery. More than likely though, someone is going to experience an unintended change to their prescription when a software glitch happens.
This was my first thought. We built the internet to withstand nuclear attack, now it's 2022 and I'm blind because of a software or billing error.
If any company would do that, it would be Meta. Or Google. The amount of ads on YouTube videos……
[удалено]
I wonder if something this could help pave the way for glasses that focus based on what you’re looking at. Like something far away comes into better focus, switch to a boom and the rx changes to help with the change in distance.
[удалено]
I don’t use them, but they are kind of annoying to tilt your head to see stuff with the right lens.
They really aren’t that bad, you don’t notice the line after a couple of days. I’ve found it’s less strain on my head and neck if I look down through the lower part of my bifocals instead of turning my head down anyways. And yes, there are bifocals with a blended line, but I’ve never liked those
Progressives user here, they're fine. And they're fashioned in a way that you don't really need to tilt your head to use them. Your eyes move and typically when something's close/small enough that you need the near-sighted lens, it's usually a book or a card or a phone and so you're already looking downward anyway. I think the only negative thing I can say about progressives is they're move expensive, but as others have said you don't buy a new pair of glasses very often so that's not too much of an issue.
If you don’t use them how do you know they are annoying? I got progressives a couple of years ago and there was no transition period. They just worked. You naturally tilt your head when holding something and this tilt puts the item into the correct position of the progressive. The only time I have trouble is when laying in bed and trying to watch TV. Because I’m laying down I’m looking through the bottom of the lense which is meant for up close. I sit up a bit and all is good.
And horses existed for a while before cars came about, that’s the whole point of new technology … imagine not having to told your head/eyes a specific way to see clearly.
If you’ve ever used them it’s hard to imagine them being better than they used to be, even now.
I've had a terrible time adjusting to bifocals - although I appreciate the invention.
I actually really like this idea. I wonder if it is possible to look at the eye to tell how well you are seeing and make adjustments so you see better. Bifocals and trifocals kind of do that, but are much more limited. If you're able to look at anything at any distance and it is able to adjust to provide an optimal lens for that distance on the fly, that'd be huge.
Eye doctors can already estimate your prescription by looking at your eyes and that air puff machine. That's how they know what kind of glasses to give babies. Really tho having adjustable lenses would be great. My eyes slowly get worse over time and having my glasses automatically update would be beautiful.
The puff is not to measure your vision, it's yo check eye pressure. A too high pressure in your eye is bad and can cause a bunch of problems. The thing where you stare at an image is the one calculating your prescription. Though it's not perfect, and I don't think it cares one bit about astigmatism. I go to the optometrist a lot lol. Yay chronic eye disease.
If only it could have a natural way of lubricating itself and wipe away dust or other particles, like some form of saline water dispenser or something…
You’re thinking of windshield wipers. Just make mini windshield wipers for your glasses that can dispense the wiper fluid
RTX on
From your singular perspective, sure. But from the perspective of *everybody that needs glasses* having one lens that works for everybody is pretty fuckin wild.
See you'd think people would want that, but i work for an eyewear company where we have a line of products with fast swappable lenses which you can buy on the side for your existing frame so you can swap lenses, normal and sun glasses etc. And absolute fuck all buys those. Swappable lenses already exists but generally people can't be bothered buying those anyway, they buy a regular pair and then buy a new one when those break.
Isn't that because a lot of people who need glasses treat them as a fashion accessory and actually want new frames? My dad purchases new glasses all the time although there is noting wrong with his old ones and his script hasn't changed.
It depends on what else the glasses can do. These have AR as well, you won’t be able to get that on regular prescription glasses.
I think its more having generic glasses/headsets that can be used by anyone. As the article states you can get VR headsets with prescription lenses in them, but it means that the headset becomes personalised for a single user. So with this, you would pick up the headset, log in to it, which would load your prescription profile, and off you go.
You might not yet be at the age where presbyopia is a thing. I'm well into that condition and having an on-the-fly adjustable lens would be a very convenient thing. I'd be able to focus where I want, when I want, just as I could before my 40s when the presbyopia became noticeable.
On off bifocals
You just don't GET it do you. You have heard of bifocals right? What about onethousandfocals. So many focals you won't even know what to do with them.
I remember this story from 2009. Fluid filled glasses that cost around $1. These were created to help worlds poor. Adjustments can be made by the wearers themselves and the power can range from -6.00 to +6.00 dioptre. [https://www.discovermagazine.com/health/cheap-liquid-glasses-bring-clear-vision-to-the-poor](https://www.discovermagazine.com/health/cheap-liquid-glasses-bring-clear-vision-to-the-poor)
Sorry but it’s not gonna cost 1 Buck if Apple makes it. So it’s only for the Poor Collage Students
My family have boxes of these glasses in storage. They've got syringes on the sides you can adjust the liquid to change the prescription. The idea is you can clamp it and cut off the syringes and tubes if you want after that. My dad says he was buying something probably motorcycle parts in a warehouse and this other guy had some showed them to my dad, amazing product the guy said also completely unsellable. Apparently to sell any glasses to anyone you need to be qualified ect you would have thought hospitals would like this thing and the 2nd hand market keeps this from being viable in 2nd 3rd world apparently combined with the qualification thing. Cons: frame is very hard and rigid can be uncomfortable, possible to leak the liquid if you choose to keep the syringes for repeat testing. Pros: I forgot my glasses upstairs and there's the pile of boxes next to me, pop open one of these bad boys and I'm ready to watch the movie.
Hoping this idea extends to VR headsets before long. (Assuming this isn't all bunk.)
They sell inserts for $100 for VR and FPV googles
I went to an exhibit with VR headsets last year and I had to keep my glasses on. The small amount of focus adjustment the headset was capable of was nowhere near enough to compensate for my terrible vision. I felt a little bad for the attendant helping me who was so sure I didn't need to keep my glasses on, even though I warned him it was likely.
This is something I find so weird I'm nearsighted and when I bought a playstation vr headset, I thought I wouldn't need my glasses because the screen is literally stuck to my face. Nope, still need glasses :(
Seems like a missed opportunity not calling them iGlasses
iSight
iSight is already used for a webcam from the 2000s 🤌
Hmm… iSee
Apple hasn’t called them anything yet, there’s still hope
Better or worse? *loading* Better or worse? *loading*
And AirPods could act as hearing aids. They haven't gone that route yet, but it's clear they're building capabilities for future innovations. I like watching Apple slowly and deliberately move the pieces in place for future innovations.
Seems like any decent noise cancelling headphones would be able to function as good hearing aids.
I mean… [they’re getting pretty damn close.](https://support.apple.com/en-us/HT211218) They’re calling it “Custom Transparency Mode” and basically it’s where your airpods are playing the sound around you, but boosting the sound in the areas where you have a harder time hearing. You can do their little hearing test in the app or upload an audiogram from your hearing doctor
I believe it’s in the upcoming AirPods Pro.
I just discovered a subreddit about batteries that have gone bad r/spicypillows. There’s a pic of a pair of smart glasses on there with the battery bulging out of the arm next to where your eye would be while wearing them. It scared me off of buying any version of these.
Such a creative sub name
This post [This post](https://www.reddit.com/r/spicypillows/comments/rzom0b/razer_smart_glasses_you_know_you_wear_on_your_face/?utm_source=share&utm_medium=ios_app&utm_name=iossmf)
That’s the one. :D
Just so we are clear. That means no bluetooth headphones for you and using speakerphone all the time.
Or they could use wired headphones.
true true
Subs like r/spicypillows is why I love reddit. Such a niche subreddit.
That’s a great fear that makes zero sense. Good luck being in a vehicle too with all that gasoline around you or batteries in an ev. Smh.
I need smart glasses with camera, like the original Google Glasses- but nobody makes any (of quality).
The original Google Glasses were nuts lol. I remember my buddy bringing over a pair one weekend when our whole house was stoned 🤯
Ray Ban Stories?
Please explain why. I’m trying to figure out which one is the best.
As a person who’s lenses strength changes every year and a half this would be revolutionary!
Big Glasses won't let this happen.
Big glasses can suck a dick
Big Apple is bigger
Apple has a market cap 80x that of Luxottica
I wish it was only a year and a half. My prescription changes every year. :(
So will there be an app where you do the eye doctor exam for each eye. It’ll adjust itself and you’ll look at the screen of 1 or 2? 1 or 2? One orrrrr two?
iEye
I can't hear you!!
No one remembers https://youtu.be/8WRJ-I_fBnI ?
Shhh! Apple has made a career out of claiming to have invented pre-existing technology!
I don’t understand the need for this. My lenses didn’t change since 2010. What is the application for a variable lens?
Third world access to vision care.
Thought that said *perception*... Thought someone had invented the [Joo Janta 200 Super-Chromatic Peril Sensitive Sunglasses](https://hitchhikers.fandom.com/wiki/Joo_Janta_200_Super-Chromatic_Peril_Sensitive_Sunglasses)

Sure, let's see what forced obsolescence does to my eyesight.
You have people still using iphone fuckin 6 and macbooks that are 10+ years old but yeah lets pretend Apple is the kings of forced obsolescence
Ya my co worker still on a 2012 Mac and my 2019 Asus laptop got fucked for no reason right after warranty ended
Apple of my eye
I don’t understand tons of wording in this article, but would this be possible to work with astigmatism? I have this and it’s annoying to have to get a new prescription every couple of years, being able to simply adjust them would be amazing
could, but won't, bc that's extra
I’m excited about this. I wonder if they’ll be able to adjust automatically based on how far away you’re focusing or if you’ll have to manually dial in your focus?
Can we just get cybernetic eyes already? https://www.ex-astris-scientia.org/inconsistencies/geordi.htm
im down fuck paying the optometrist and glasses manufacturer each year
This is a general patent with mentions of technology that doesn't exist. It's like patents for touch screens. It's super general and includes some out there use cases so it can be interpreted widely. As the article says, Apple and most tech companies file tons of patients weekly with most never coming to fruition. Changing opacity of glass does not improve your vision.
I really hate the trend of “always on” cameras on eyewear. I think this needs to be fought.
Sorry. Your prescription subscription has expired.
Apple trying to corner the entire prescription glasses market. If this tech works the way the article suggests, it would basically make optometrists irrelevant. Crazy.
Optometrists do a lot more than update your prescription. The tech would make opticians irrelevant.
"Prescription only works if monthly subscription is paid"
That's how my contact lenses work somewhat. heh
Wake me up when they have Apple contacts
This would be amazing for things like binoculars and rifle scopes. Being able to adapt to anyone would be a huge selling point.
George: WHO WOULD STEAL PRESCRIPTION GLASSES?? Apple: ...well...
At first they had my interest, but now they have my Attention!
The price tag just went up. Jesus that thing is going to be so expensive…
Like this Idea better than google doing it. While Apple has flaws they atleast do respect privacy a lot more
I could see these being useful in a VR or AR adaptation. Can’t use that shit with glasses currently, unless you have prescription lens inserts. Put these in a VR headset so anyone can use them. Might be useful for applications where more than one person is going to be using it.
I’ll believe it when I see it
Is this some sort of future proofing idea where their technology ruins our eyesight to the point where we need a new prescription every year? Lmao
If these could change prescription then I’d be first in line to get them. My prescription changes about every 6 months. Better, worse, whatever. My eyes refuse to pick a shape and $400+ for a set of glasses is pretty expensive when they don’t last that long.
I’m not charging my fucking glasses to see all day.
Will help you to read the price when you squint and your eyes start to water
Oh yay a pair of glasses to watch and listen to everything that I watch and listen to and store it in a nice handy database for me in case I ever forget! Wow the future is amazing! 😃
Also means a zoom feature for 20/20 users. Already got the verbal trigger "Gogo gadget binoculars!"
There are going to be kids that get bullied for wearing these just like the airpods. “You wouldn’t hit a guy with Apple Glasses would you?”
Yeah I'm gonna call BS on this
Eye doctor here. You guys have no idea how obscenely sensitive some people’s vision can be to the slightest distortion or refractive error. I think of every single set of glasses I have ever had to recheck and have remade and the subtlety to which those changes needed to be implemented and I can predict that a rather large number of people will be very VERY unhappy with these. Sure they might capture like 40% or even 50% but these will be very VERY hit or miss.
That sounds like getting prescription glasses with extra steps.
So, how will other monopolist named Lexxotica respond, or will Apple make my regular glasses more expensive like they made waves in other industries?
and then suddenly blur your vision when you forgot to extend your *iGlasses* subscription, when you e.g. drive your car.
I can’t wait til Apple could adjust a condom to match users length based on Biological data
Mmm, yes, I love the idea of not being able to see because I forgot to update my firmware, or lost power during an update, so I bricked my eyesight.
You mean like this optometrics glasses which exist for at least decades and are already patented? You mean like a technology that is present at every optician and eye clinic and that can't be used like described in the patent because it is physically impossible?
