Off on a complete tangent here, only remotely related.
Yo, fellow four-eyed geeks.
I noticed that when lying down and looking up in a room with a light source, with my glasses on, if there is a small droplet of water on the lens (say, due to having just cleaned the glasses and not wicked up every last drop), this droplet can bend the light in such a way that when it subsequently hits the cornea and pupa, a perfectly straight, parallel beam of light passes through the vitreous humor right to the retina.
The consequence of this is that all the junk floating in your eye is rendered in "4K clarity" in a circle of light, regardless of whether it is next to the retina, or floating somewhere in the middle.
Imperfections in your cornea or elsewhere are also rendered, making themselves evident.

Correcting? They mean temporarily cure... If this works, it's fascinating!
One thing I have been wondering for a while, and I thought this what it was when I read the title, is, why can't we have zoom lenses with a camera turned inword to the retina applying autofocus algorithms? As I age, I need a different prescription for every 20 cm I push my laptop back, something like this would be very useful.

BTW: -2 shortsightness is the optimal. You can see your own hands and what you are doing and eating until the day you die. I happen to be those lucky few. On sunny days the iris is so small I can manage without glasses.
As a myopic person wearing glasses for 25+ years, I'd like independent verification of these claims. There are/were a number of similar devices that turned out to be a total dud.
It looks like the article doesn't have any details on how this works, anybody care to speculate on a potential mechanism here?
I have a lot of questions, but I'd definitely pay if it worked. I've very slowly been getting more nearsighted, but I mainly avoid wearing glasses. My optometrist said that wearing glasses would speed the slide, although I'd eventually end up at the same level of myopia. I'd much rather wear glasses that fix the problem than make it worse.
Some additional information here:

Assuming this device is actually legit (I'm skeptical...), it would need e.g. FDA approval to be used in the USA, correct?

On a related note, I find it super interesting that people across many communities and forums report seeing eye sight improvements from daily use of VR headsets. Though it can take a while from those accounts I read, like average 1 hour a day for a year. In each case these people report not wearing glasses in the headset.
Has anyone here given this a try: https://gettingstronger.org/2010/07/improve-eyesight-and-thr...

It claims that myopia can be cured, just like muscles can be made stronger in a gym.

For those interested, there are a couple of treatments available in the U.S. to slow the progression of childhood myopia. MiSight[0] contacts and low-dose atropine[1].

Neat.
My prescription changes every couple of minutes. But along a predictable curve.
I keep thinking about getting optometrist adjustable lenses hooking it up to motors to automatically shift the lenses. Mechanical is beyond me though.

"It projects an image from the lens of the unit onto the wearer's retina to correct the refractive error that causes nearsightednes" so regular glasses then...
Interestingly enough, an older comment mentioned a study in the 1980s observed that people in submarines develop myopia:

so adults (possibly young adults) do get it

Shut up and take my money. This is the smart glasses that the world needs.

Alas, I'm cursed with mostly astigmatism.
Pay walled.
Damn my long-sightedness!
Reads like snake oil to me. I'd love to learn how this devices reshapes your eye lens when not worn. There are methods out there that people swear by, but I haven't seen a drop of evidence. I'd jump at the opportunity if it worked.
It's not a great headline. My first reaction was "that's what glasses do".
Poor choice of words; the headline should read "Myopia treatment 'smart glasses'..."
"Eyeglasses" are considered corrective lenses in US (at least) usage (because they correct the distortion of the body's lens).

Maybe some of you will find this beneficial if you have slight vision issues. It’s anecdotal, I don’t have scientific backing here. It worked for me, and I think it’s harmless to try. What I’m about to describe is what I think is the Active Focus method.
I’ve always had perfect vision but my dominant eye degraded slightly over the years so I looked into how to bring it back to full. No one in family wears glasses or anything like that, although the elderly use reading glasses of course.
Practicing reading on both monitor and in front of a book with the good eye palmed and trying to shift the focus back and forth while gunning for more clarity for a longer period of time, it took me very little to get rid of the issue - I must have practiced probably 30 times of a few minutes each over the span of a few months, so maybe once every 2nd or 3rd day as I felt like it. I went from having a hard time reading the numbers and letters to very carefully observing the edges of fonts rendered by ClearType antialiasing on Windows.
At first the eye muscles got strained from me forcing it to focus, but then it got better. Minor soreness and redness at first is nothing to be concerned about IMHO. I still practice but not as often, since I’ve trained the ability to focus at will which is really what active focus is about from my understanding - intentional focusing with enough speed.
I’m not a big fan of EndMyopia but the subreddit has people claiming they fixed far worse problems than I have (if slight blurryness is even worthy being called a problem).
I highly recommend Todd Becker’s presentation on Active Focus for anyone wanting a breakdown of the approach. Some people seem to have a hard time with being able to finely control where their focal plane is. It gets easier with practice is about all I can say.
The full “method” that Todd Becker and EM recommend is to try to keep distance to whatever that you’re reading so that it’s just slightly out of focus, but I haven’t had that severe of a myopia. From time to time I read sites like HN from slightly further away than usual just to provide a bit of a challenge to the focus practice, but I think long term it probably isn’t healthy to try to read HN at normal font size from across the room.

now if only they had something for astigmatism. There's surprising lack of progress

This headline is a classic example of "burying the lede". Er... glasses that correct myopia? Haven't those been around for, like, at least 600 years?
BTW there was an interesting article on Myopia yesterday on how Covid lockdowns will harm children's eyesite.

This will absolutely not, under any circumstances, "correct" myopia. You can only slow its progression, with techniques like:
- Pupil dilating eye drops
- Wearing corrective lenses as little as possible
- Wearing glasses with fogged edges/rims
- Reducing the time you hold objects close to your face
The major factor behind all of this is to reduce the over focusing of light on your retina and fovea. The more light that focuses back there, the more your eye is told to grow longer.
Every parent should know this and how it works. And so should your ophthalmologist, most of which are clueless.
You can't, in any way, undo this growth once it's happened. This is terrible reporting.

Before looking into this, I would have guessed 2X or 3X, but would you believe it's actually over 100X!
I bet most people's guess would also be off by 1 or 2 orders of magnitude.
Even outdoors in the shade, it is over 50X brighter than indoors.
(For specific numbers and comparisons, see: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6656201/ )
Apparently, our eyes adjust so quickly to the difference that we have a very poor sense of the magnitude of light change between indoors and outdoors.
I bring this up because one of the largest factors in myopia development appears to be outdoor light exposure in childhood.
Genetics are likely a factor too, but light exposure seems to have a huge effect: "The prevalence of myopia in 6- and 7-year-old children of Chinese ethnicity was significantly lower in Sydney (3.3%) than in Singapore (29.1%), while patterns of daily outdoor light exposure showed that children living in Singapore were exposed to significantly less daily outdoor light than Australian children." (from the same study linked above)
The obvious takeaway for parents, schools, and governments: ensure your children have plenty of outdoor playtime. It will greatly reduce instances of myopia (not to mention the benefits from higher Vitamin D levels, exercise, etc).
