The reason for widespread short-sightedness is unknown but the best study I read showed that kids playing indoor sports have significantly worse vision compared to the same outdoor sports.
My theory is because we look up close frequently, our eyes become adjusted to it. As a very near sighted person I can tell you, I see much better very close (a few inches from my eyes) than someone with 20/20, like magnification. Try it. I also used a screen probably 8 hours a day even since early childhood (lol, 90s parents).
We are really well adapted for pre-history and there’s evidence we were happier and healthier back then (murder/rape was common, though). “Sapiens” covers this fantastically in general.
Back when I first had to get glasses I had been spending as much time outside as I possibly could. It’s just something genetic and has nothing to do with how you look at things. The reason our ancestors survived it was we lived in tribes and helped each other out.

That magnification effect is why I don’t want lasik, it’s like my little superpower.
Plus the whole eyeball surgery thing.
It’s the smell of burning eyeball for me.
Some research postulates it’s the lack of sunlight.
