Pretty funny! But the reason so many people need glasses is because we spend all our time indoors, reading. People in the past were outside working all the time and they didn’t need glasses as a result.
Is that true? I feel like it simply wasn't an option, so people didn't get them.
There is some truth to it, but there's also just the fact that some people's eyes are bad enough that they need glasses to fully function in modern society, but not so bad that they couldn't survive in the wild without them.
Me for example. I need glasses to drive, I can't read street signs otherwise, and I need them at work, but I otherwise usually don't wear them. The only thing better eyesight would meaningfully help me with in the wild is navigation and spotting hidden animals quicker, and even then it'd really only help with snakes. Any other ambush predator I'd be likely to encounter in my region is big enough that spotting it a few seconds sooner wouldn't really help.
