Why do most Asians wear glasses? If bad eyesight is in their genes, wtf did they do before glasses were invented?
There may be genetic reasons. Or the fact that they are subject to long hours reading and writing from an early age.
In the past there was no this mania "education for the masses", kek. Near-sightedness is limited to the very few who could read at all. And they did not write in such small shape which helps.

To make their eyes look bigger.
Distance focusing is the result of muscles squeezing your eyes in different directions. The ones for looking far away atrophy if you don't use them.

>reading makes your eyesight worse
Could you be any more fucking retarded?

Literally just as an accessory. There aren't any lenses in those frames. Otherwise you'd be able to differentiate an outline of the side of his head refracted through the glasses.
You'd be surprised how many people do this.

Apparently it might have to do with sunlight exposure to the retina during childhood

>Individuals who spend considerable time reading, working at a computer, or doing other intense close visual work may be more likely to develop myopia.
I have posted on this many times on /sci/, and very few pay any attention. There was a very interesting nature article on this specific topic some years ago:
https://www.nature.com/news/the-myopia-boom-1.17120
>For many years, the scientific consensus held that myopia was largely down to genes. Studies in the 1960s showed that the condition was more common among genetically identical twins than non-identical ones, suggesting that susceptibility is strongly influenced by DNA.
>But it was obvious that genes could not be the whole story... One of the clearest signs came from a 1969 study of Inuit people on the northern tip of Alaska whose lifestyle was changing. Of adults who had grown up in isolated communities, only 2 of 131 had myopic eyes. But more than half of their children and grandchildren had the condition.
>By fitting chicks with goggles that alter the resolution and contrast of incoming images, it is possible to induce the development of myopia while raising the birds under controlled conditions in which only light intensity is changed.
>Retinal dopamine is normally produced on a diurnal cycle — ramping up during the day — and it tells the eye to switch from rod-based, nighttime vision to cone-based, daytime vision. Researchers now suspect that under dim (typically indoor) lighting, the cycle is disrupted, with consequences for eye growth. “If our system does not get a strong enough diurnal rhythm, things go out of control,” says Ashby, who is now at the University of Canberra. “The system starts to get a bit noisy and noisy means that it just grows in its own irregular fashion.”
