> My suspicion is that staring at objects closely and under dimly lit conditions causes pseusdo-myopia
Are you implying that cell phones could be a factor?

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.
Your theory about 20 ft is literally correct.
Atropine is successfully used to relax the cilliary muscles.
However, there is lots of anecdata that rigid contacts don’t make your eyesight worse over time.
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.
I dont understand why people especially shortsighted people still use the same glasses for everything. Why don't octometrists know better?
Its a horrible user experience
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.
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.
And yes, most will just use short-range glasses all day as their only pair, which is exactly the thing you insisted that you did not understand ("I dont understand why people especially shortsighted people still use the same glasses for everything. Why don't octometrists know better?").
Sometimes it might make sense to just ask those with the handicap rather than make baseless assumptions about their situation as an "outsider".
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.
Bad UX for switching, and my "reading" glasses have too short of a clear vision range to use at my computer without having to lean in.
It's just a comment that so wrong it's not wrong.
Prescription glasses restore your range of focus to original which is why I said it aims for looking at far objects, at relaxed eyes.
Problem with myopia is that you overwork your eyes' muscles by staying in close focal lengths too long.
And books, too.
