Some of the online stores especially the ones based in China don't actually check your prescription.
Do you have any recommendations?
Some additional information here: https://www.kubotaholdings.co.jp/en/ir/docs/20201216_EN_eSpe... Assuming this device is actually legit (I'm skeptical...), it would need e.g. FDA approval to be used in the USA, correct?
There's an interesting paragraph in there: "myopic defocus is already in use in the US with a contact lens, “MiSight® 1 day” by CooperVision, which is U.S. Food and Drug Administration (FDA) approved to slow the progression of myopia. This product, which uses multifocal contact lens technology, passively stimulates the entire peripheral retina with light myopically defocused by the non-central power of the contact le…
What's the "nanotechnology" they are using, and how would that relate to the device's function?
I'll see if I can find blockchain and machine learning somewhere in there.

I don’t know whether you know, but +3.25 isn’t near-sightedness (myopia), but far-sightedness (hyperopia) or presbyopia (Wikipedia: “insufficiency of accommodation associated with the aging of the eye that results in progressively worsening ability to focus clearly on close objects”) I don’t know whether you know, but +3.25 isn’t near-sightedness (myopia), but far-sightedness (hyperopia) or presbyopia (insufficiency…
I didn't say that it was myopia did I? I specifically gave the glasses strength with the sign to indicate the kind of correction my eyes needed, and yes, it is far-sightedness, what else could it be with that particular prescription? Hence my need to wear them when working in the shop, I'm chance less without them doing any closer or detailed work. The point was: once you start wearing glasses it accelerates the slid…

It's making a mountain out of a molehill. Yes, there's some evidence that very rigorous, regular eye exercises can help delay or even slightly reverse myopia. Slightly. If you give yourself a headache for like an hour a day, every day. And the effect goes away when you stop exercising. This is something that has been studied pretty extensively. If it was actually a cure, it'd have been well-proven by now, and we'd al…
> If it was actually a cure, it'd have been well-proven by now, and we'd all be doing it. You could say that for everything for which there was no treatment before and for which the problem is now considered solved with modern practice.
Ask yourself, how much brighter is it outside than inside (assuming a sunny day vs a brightly lit office)? 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…
When my 5yo kid's eye check came back with "he'll need glasses next year", we started strict "hour+ outside play daily" policy. At his next checkup, he had normal vision. Dr was surprised.

I used to live almost on the equator. Before adolescence, I would spent most of my time outdoors. Very stable weather so windows were open most of the day (and night). There was often direct sunlight even indoors. We would go to the beach every weekend. I ended up with -5.00 and -5.25
Maybe this would decrease the prevalence, if you are looking at the entire population. But it's not like you, as an individual, will be immune if you just stay outside.

A day or two if you're lucky. If you happen to have corneas like mine, you'll get about 9 hours before suffering a fast decline: https://news.ycombinator.com/item?id=21546732 No lasting bad effects for me, at least. I'm still glad I tried it.
Isn't there a period of time during this decline where you can't wear your normal corrective lenses because they are too strong? That sounds horrible.
The other thing that really bugged me was the fact that these lenses could not correct my vision across my entire dilated pupil, and that issue also got worse as the day went on. That resulted in terrible halos around light sources in high contrast situations, such as at night when driving home from work.

It does seem like a convenient "just-so" anecdote, and I've never experienced or heard of myopia just going away like that, but I also don't think it sounds completely implausible.
I'd imagine it's also less noticeable in scenarios when you don't need to read smaller letters from a distance as much (ie: when you are playing outside rather than sitting in class).
So the perception that you see more clearly in bright outdoor conditions could be true.

I've read this study a while ago, and I think it helped me correct my son's myopia. When my 5yo kid's eye check came back with "he'll need glasses next year", we started strict "hour+ outside play daily" policy. At his next checkup, he had normal vision. Dr was surprised.
- 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.
