I believe, like many things it's a combination of things. Cultural, genetic, biological, environmental... Anecdotal evidence would suggest that our increased time spent reading, writing, working on computers might cause undue strain. That isn't to suggest that hunter gatherers didn't spend time working with things arms length away but they did spend more time seeing much farther. Agriculture, industrialism, and specialization has diminished the effect of survival of the fittest therefore allowing people with poor vision to contribute to the gene pool where previously they would have been culled out.

Nope, they drank straight out of the bottle...

Nope, myopia is a neolithic disease - any hunter gatherer that had really poor eyesight was tiger food - evolution's a bitch, if you don't meet it's stringent requirements, you died quickly.

No. Eye correction is a disease of civilization. Myopia is virtually absent amongst the Inuit or in Kitava.

Obviously the roads were less crowded so you could drive your dinosaur without fear of bumping into the next guy. But seriously, I think eyesight probably degrades due to overuse such as reading and failure to use your eyes in a varied manner. Watching tv at a fixed distance several hours a day or staring at a computer screen can't be good, I better stop here.

Very possible that they didn't notice a need for any kind of correction because they didn't have signs to read, blackboards, movies, etc. They just had to hunt at a distance and maybe Grok came back to the cave empty handed and said I didn't see anything to kill today. Whereas Bronk came back with a tiger because his eyes were 20/20.

Fun stuff.
