I went pretty deep down this rabbit hole for a while. I've always been suspicious of eye doctors since every visit they find an excuse to bump you up a notch or two. Anecdotally, me and my brother had the same prescription in high school. I started refusing to go to the eye doctor. He kept going. I happened to see his contacts prescription maybe six years later. His prescription was now over a diopter stronger than m…

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.

It's amazing what the eye can adapt to. The story of the man who wore the glasses that turned everything upside down... and his brain just adapted to it and he saw things normally... is fascinating to me.

And then there's my eyes. I have severe double vision (as a result of surgery last year) and my brain is just like "meh, suck it up"; and I'm left walking into things on regular basis because there's two of everything. How come _his_ brain figured out upside down, and mine can't figure out 2 of everything? (I'm not actually asking, just complaining a bit /sigh)

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

Ugh. I had fairly stable myopia and was content. Recently developed astigmatism in my strong eye and so my overall vision is substantially worse.

Anyone know what can cause sudden onset of astigmatism in adulthood? It appeared a couple years ago and seems stable. Not sure over what period it appeared, probably in 3-12 months.

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.

Anybody knows what happened to this project https://www.core77.com/posts/12220/brilliant-water-based-eye... ?

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.

It's also your age. I kept having stronger and stronger glasses (until -9.5) but then it suddenly stopped and vision stayed at this one point.

This was also what a eye doctor said to me ~20 years ago, although his prediction when it would happen didn't quite match.

The same thing happened to me where I got continually stronger prescriptions, but I stabilized anyways at around 18. My optometrist told me that's very common after adolescence.

I really wouldn't recommend using an incorrect prescription. In the US anyways shops won't let you use a prescription older than 1 year.

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.

I meant that you can discuss it with your doctor to get their factual knowledge or pointers, and then draw your own conclusions. I didn't say, and didn't mean to say (sorry if it came across like that), that you should follow their advice to any degree. I trust the overwhelming majority of people (doctor or patient) to use their own reasonable judgement, and the rest won't be helped by this advice anyway.

And for what it's worth, you may have had a string of bad doctors. I never had that feeling with any of mine (though I've only ever seen doctors in the Netherlands and Germany).

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

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

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.

> making a profit from glasses being sold is likely to impact how likely the doctor is to prescribe new glasses.

And beyond that, following the logic from the recent surgery thread: they see their patients see better. They see all the good cases, where someone walks out more confident and with better sight. Their product helps people. But then so do homeopathic placebos (to a certain (measurable) extent), and that's the hard part to figure out.

Of course, in this case everyone truly does see better when they walk out and what GP is wondering about are the long-term effects. This stuff is complicated, though I frankly have a hard time believing this claim of "just stop wearing glasses and you'll see better". Surely someone would have noticed that? But without doing a deep dive into the research here, it's all just speculation on both their part and mine.

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-si…

As a kid, I remember that my myopia disappeared after one summer when I was outdoors a lot. Then it came back soon after returning to school.
