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 truly has an environmental component to it

Very much possible. I only have anecdotal evidence, but if you plotted the amount of time I spent at home starting at a TV versus other kids, you will probably find interesting correlations.

> , e.g. childhood eyestrain and video games.

Why single out video games in particular? If there is a problem, the problem is the screen. Or rather, how close it is. It is unlikely to be related to the content.

I wouldn't be surprised to learn about a feedback loop getting disrupted. For many organs in the body, an approximate shape will work just fine, who cares if an organ is slightly off by a few millimeters. Not so for the eyes.

It's true. I went from pretty good eyesight to +3.25 over a relatively short period of time, but it wasn't an option to wait any longer, I had these crazy headaches and did not realize they were caused by my eyesight being off. The initial glasses were +1.5 and made a world of a difference. 6 months later is was +2.0, another six months and it was at 3.0. That's when I got scared wondering how bad it was going to get…

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 slide. + or - doesn't really matter all that much.

> "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 t…

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

As an adult, it would certainly be an outstanding discovery if this did matter. Which is why I'm skeptical about these supposed glasses. Sounds like snake oil, quacks like snake oil.

For children, teenagers and young adults: maybe. It's all about the eye shape, and children's bodies are still in development.

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…

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).

Ok, we'll use that above. Thanks!

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.

If this worked I would take a loan if that's what it took.

Most likely snake oil. Even more so since they are calling it "smart", I'm surprised there's no blockchain.

Extraordinary claims require extraordinary evidence. This thing can somehow physically reshape the eyes (or the cornea at least) permanently, with no surgery.

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.

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.

That is a trial with N=1

Your eyesight might have stopped getting worse on its own. As is the case for most people (myopia doesn't run away to infinity after all!). Which is why corrective surgery is only indicated after your prescription has been stable for some time.

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…

Was this in the US? I’ve tried and everyone told me filling an expired prescription is illegal. Even places that don’t do exams. I have an old prescription and don’t want to get an exam because of the pandemic.

That doesn't make sense.

I'd recommend getting glasses online from Zenni [0]. They just ask for the measurements of the prescription. There's nothing about expiration dates. And they're super inexpensive! Glasses are a racket.

I can't speak for the quality/durability of their frames, as I only used them to get some prescription lenses for my Valve Index so I can play in VR without wearing my glasses.

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

Do you have any recommendations?

I use firmoo, and I haven't had any issues with the lenses. The only tricky thing is that you need to basically estimate the fit based on the dimensions of glasses frames that you already own.
