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.
My understanding is that being nearsighted is a relatively new phenomenon that is largely due to being indoors a lot. Farsightedness in old age has been around since humans have been humans.
I took a quick look and Wikipedia partially bears this out re: nearsightedness.
I was born with bad eyes. People back then also were born with bad eyes but couldn’t do anything about it.
Obviously you can also get bad eyes (shortsighted) when always only focusing on short distances but it’s not the only way. Most people also become far sighted when they get older (the pressure inside your eye lowers and therefore your eye becomes shorter)
Focusing close regularly doesn’t make you short sighted, not getting enough tourquoise light on your retina from staying inside makes your eye keep getting longer instead of stopping when the focal point is correct. Well, that and genetics.
And losing the ability to see near as you age has nothong to do with pressure. Your lens is constantly adding new layers to itself to stay clear, and after 40 it’s become so thick the muscles that pull it to accommodate near vision can’t stretch it enough. By 58 it doesn’t stretch at all any more. That’s why everyone eventually needs bifocals/progressives.
Don’t state things as fact if your not sure of them.

Is that true? I feel like it simply wasn’t an option, so people didn’t get them.

My biggest pet peeve in internet is people who state something as a fact eve though they are just really confidently wrong
