Considering how much it would’ve affected hunting and gathering, how are so many people nearsighted?
In: Biology
The vast majority of nearsightedness isn’t very strong. It can hurt the ability to read tiny letters or make out small details, but those aren’t really needed for hunting or gathering.
Also, reading or looking at screens a lot during childhood, when your eyes are still developing, cause cause or worsen nearsightedness. It’s a lot more common in modern society than it was back when hunting and gathering was a significant factor for the average person.
