That wasn't my intention, although I imagine they do play a role.
The human eye (specifically the ciliary muscles) are most at "rest" when staring at objects in the distance.
The human eye doesn't seem to be as well-suited for staring at distance less than ~20 feet for long periods of time.
I imagine learning how to read and write in general, the shift from an agrarian society to cognitive labor, and the invention of glasses all were just as important factors.
just guesses, because they are so infrequently worn these days, is that it somehow prevents eyeball deformation due to its rigidity and so the axial elongation does not occur.
I'm a little sceptical about that theory, but my own rx did not go increase much when I wore RGPs. After that I did have some progression, but also a million other things changed, so who knows.
RGPs however, are quite distinct in that they give absolutely perfect vision. better than soft contacts by a mile. Maybe some refractive thing as well, optometrist told me numerous times under-correction would lead to further progression.
Ortho-K is popular in Asia for prevention, those are rigid lenses worn at night. Deforms cornea a little, so it's like a reversible lasik thing. So, in this case, not only its rigid lenses, they also have weird geometry. Many report significant success.
People whould wear reading glasses even before myopia. And when they do get myopia, they should NOT wear prescribed glass while reading/working, but a reading glasses that factor in their myopia.
I dont understand why people especially shortsighted people still use the same glasses for everything. Why don't octometrists know better?
People wear the same glasses for everything because it is hard remembering where your glasses are, carrying them around, and swapping back and forth every couple seconds.
You only look at things relatively close to you from 9 to 5? You don't have computers or TVs at home? A smartphone? Cooking instructions?
It's not a hyperbole, glasses are massively inconvenient to those of us handicapped without, and having to hot-swap then depending on subject is massively more inconvenient.
It's hyperbole because you consistently ignore the fact that eyes can change focus for the short term, that's like the one thing they do. It's straining your eyes for long periods, at the same focal point, such as while working, that we need to help with.
PS: you are right, maybe instead of only at the desk, just wear a "near sight" pair all the time, when you're indoor, and a far sight pair when you are out. Point is you dont have to hot swap.
Well I have -2 diopters glasses for myopia, started wearing them around the age of 30 I think (I am now 44). I never use them when reading, effectively they bother me. But have to use them when using the computer monitor, otherwise it's either blurry or have to get too close for comfort. It's a continuous "put the glasses" when looking at the screen, take the glasses when scribbling a paper or reading a book / phone. Got used to it.
Also don't use them while walking, they bother me. I feel like my eyes dry out or something, very unpleasant. It's a bit blurry but don't really notice it, also -2 is not really advanced myopia. I can't read car plates from the distance but I sure see the car coming and know not to bump into people.
I'm not terribly short sighted but also can't see clearly further than about 20cm. I have to use them for everything. I think far sighted people tend to have a more usable range of functioning vision left.
Why do I need glasses for reading if I'm nearsighted? Unless you mean "ignores" nearsightedness and corrects astigmatism only? (Those are what I use for computer use, when I bother to wear them.)
I don't mean literal reading glasses, just apply the same principle: glasses designated to a task, which for most people would be using computer. All prescription glasses are for your "resting" vision to be on far objects. You'd want the resting vision to be on the computer.
If you are myopic, you are not supposed to wear glasses for reading, but most people I know do this, which just worsens it. You are supposed to be without them for as long as you can.
Yes that is if you are not advanced. One you are no longer able to read without glasses you should have a differrent prescription just for computer/reading
