Yes, I tried in my 20s with no obvious positive result.

The "myopia is purely genetic" zeitgeist has been continually shoved down all of our throats in the west. Meanwhile, studies from Taiwan, Japan, and Korea show that myopia truly has an environmental component to it, e.g. childhood eyestrain and video games. It's also undeniable that myopia manifests more in middle class workers than working class, which indicates some sort of systematic environmental component. Since…

The predisposition to myopia is genetic but one becomes myopic due to an environmental factor: the lack of exposure to sunlight. It is because of the lack to regular exposure to sunlight that people who study and spend a lot of time in homes can develop myopia if they are genetically predisposed.

Focusing on nearby objects does not lead to myopia. Doing gymnastics with the eyes has no effect. Likewise, using under-sized glasses has no effect on myopia.

Here a supporting article about Inuit populations developed myopia just in one generation because of changes in lifestyle reducing outdoor activities:

In my family (n=basically_none), it seems that myopia correlates strongly with habits. The most bookish, indoors-y kids ended up in glasses - and the more so, the thicker the glasses - while folks who spent their childhoods running around outside tend to have 20/20 vision. Assuming such an effect really exists, I expect it would be very difficult to statistically distinguish from straight heredity. Kids' early childh…

I read that being in the sun when you're a child and your eyes having to adjust with the change in brightness helps with reducing myopia

The other hypothesis I've heard is that it's switching back and forth between focusing on close-up things and distant things. Which you naturally do a lot when engaging in outdoor activities, but basically not at all when staring at books or screens.

From the article: It projects an image from the lens of the unit onto the wearer's retina to correct the refractive error that causes nearsightedness. Wearing the device 60 to 90 minutes a day corrects myopia according to the Japanese company.

How does this actually help treat nearsightedness when not wearing it? Does it change the shape of the eye ball?

It's probably based on the theory that over a longer time frame the eye adapts to slightly defocused images in order to bring them in focus. The key is that the image must be defocused only slightly, not grossly.

Warning to anyone taking the above as medical advice: perhaps it might work for you, but do discuss with your doctor and check that you are not driving vehicles with worsening sight while believing it's fine. By all means try it, but get it checked so at least you have the data to know whether it works for you.

> but do discuss with your doctor This requires having a doctor you trust. My experience with most doctors is that I can trust them about as far as a used car salesman.

Start by finding an eye doctor that doesn't have a glasses shop attached, imo. Or one that isn't "attached" to such a shop in a way they would profit from it, I guess. Without insulting any doctor in specific, my thought is that making a profit from glasses being sold is likely to impact how likely the doctor is to prescribe new glasses.

The factors weren't "childhood eyestrain and video games". The one consistent factor was the amount of bright light exposure in a study[1]; in other words, being indoors, away from bright sunlight, which is correlative to eyestrain and video games, not causative, because people tend to do those things indoors. If you read outdoors in bright light, it's not really worse than just hanging around in bright light.

Couldn't find a non-paywalled PDF, sorry, but here's the original study:

Also, it might have changed since then (2012). If there's since been a study refuting this one, let me know, because it's nigh-impossible to find between the glut of citation-free news sites and blog posts, and paywalled journals.

I have bad myopia (around -5) both my parents have it too and to me it has always been evident that it isn't purely genetic. I think I could willfuly downgrade my vision if I concentrated.

Not sure if it'll help, there's an older gentleman on Youtube who claims reading with glasses actually makes myopia worse with time, due to the way it affects the shape of the eyeballs. Look up Tod Becker.

Anecdote: I used to get new glasses/prescriptions every year. Every year my prescriptions would get stronger. Last couple of years I stopped renewing my glasses and whenever I absolutely need to get new glasses, I have the store use my old prescription. For whatever reason, my eye sight stopped getting worse. I think by wearing stronger prescriptions, your eyes adapt to it and you get more and more myopic.

Your experience is similar to mine. I got glasses at the age of 13, but didn't like wearing the glasses, so never did. Both my late father and my sister (since she was about 12 years old) have to wear thick glasses. My sister started out about the same eye power as I did, but she wears her glasses everyday. My sister's glasses got thicker year over year, and finally she got LASIK a couple of years ago. My sister doesn't work with computers whereas I spend ~10-12 hours a day with computers/TV screens (when I use computer, I don't wear glasses and my eye doctor told me that's okay). For me, my eye power stayed about the same and never got stronger glass prescription over the last 25 years or so.

Having said that, I started wearing glasses about a year ago when watching the TV between 10pm-12am (thanks to my wife who likes watching movies and I joined in). Turns out, my eyesight (near-sight) got a bit worse in a year and now I have a slightly thicker glasses. Again, this is all anecdotal and maybe age comes into play here with my eye sight (but the common knowledge--not sure how true that is--is that the nearsightedness gets better as people age, so what I'm experiencing is the opposite).

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…

I have a pair of glasses to sell you which can fix that...
