Has anyone here given this a try: https://gettingstronger.org/2010/07/improve-eyesight-and-thr... https://gettingstronger.org/2014/08/myopia-a-modern-yet-reve... It claims that myopia can be cured, just like muscles can be made stronger in a gym.

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…

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.

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…

> "myopia is purely genetic" I have never heard that Myopia is purely genetic. Where is that claim even coming from?

From tons of articles, medical advices, etc. that insist that "you don't develop myopia from reading, monitor work, video games, etc".

They not not say that it's "purely genetic", but that's the impression one gets, that all those lifestyle params don't play any role...

Wikipedia says it's "a mix of genetic and environmnetal factors", and includes all of the above factors I've mentioned. But I've read many times in the past decades articles insisting that those other things don't matter (and presenting it as the medical consensus)...

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-si…

Daytime sunlight is not the only exposure factor correlated with myopia. Nighttime artificial lighting is also a negative:

Also sounds like the prescription is not too bad. Those of us with -5 and under do not really have a choice not to wear corrective lenses :)

It's fluctuated from -4.5 to -2.5 over the years. Currently on the better end I think, but I haven't been to an exam in a long while. I have friends with lower than -5 and from trying on their glasses, I would also wear them if my vision was that bad. Even at -4.5 the only major annoyances were street signs and confusing people from far away though.

That's insane to me, I'm at around -3.5 and I feel highly handicapped when I don't wear glasses. I most definitely wouldn't drive without them for instance.

There may be some correlation but there must be other factors. Doesn't fit my history. I'm myopic, -6.0 diopter, needed glasses starting in 2nd grade. Spent a lot of time outdoors as a kid (no computers, 3 channels of TV which was targeted at grownups except for Saturday morning). Being inside was boring . Nearsightedness also runs in the family on my fathers side, but strangely none of my kids need glasses and they…

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.

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…

OTOH, perhaps those who are starting to have myopia aren't going to want to do outdoorsy things because they tend to require far-seeing. If I can't see what's going on far away, I'm not going to have a fun time with most sports, and I'd rather read a book.

How do you get stores to use your old prescription? I’ve had no luck with that.

I asked the optometrist. He was a little offended that I wasn't going to use the new measurements but I pleaded with him enough that he relented. One very interesting thing that convinced me to start doing this: if you get measurements taken at night (vs early in the day), your prescriptions will be stronger as your eyes are already tired. So your new glasses may be too strong for you but your eyes will adapt to it a…

An optometrist in Germany told me the same regarding measuring eyes in the morning, for what it's worth. I came in after work and they basically turned me away because they didn't think I'd get a good measurement at that time.

In my experience, wearing glasses that are either too strong _or_ too weak for your myopia will lead to headaches. Lots of headaches.

Some of the online stores especially the ones based in China don't actually check your prescription.

Do you have any recommendations?
