OP is right, nearsightedness has been attributed to “not being outside enough” while your eyes still develop (aside from genetics of course), something to do with not getting bright enough sunlight for multiple hours as you are supposed to.
It looks like most of the short sightedness is caused by lifestyle since it is much more prevalent in places where children spend a lot of time indoors
The others would have affected our ancestors as much as us
