20 years ago I was injured in one eye. Without an operation it would have left me going slowly blind. The operation was invented maybe 20 years earlier.
Both my eyes had a cataract at a quite early age. Artificial lenses where invented AFAIK 50 years ago. The new lenses even correct my shortsightedness and astigmatism!
So if I had lived only 50 years earlier I would be blind on one eye and quite possibly without a lense or at least seeing really foggy on the other. Now I am sitting here with - 0.5/-1 and otherwise great eye sight.
There are no words how grateful I am for the wonders of modern eye medicine.
Similar thing happened to my dad. He was slowly going blind from cataracts, like he couldn’t even make out the dinner table in front of him. He just wasn’t mentioning it until it became untenable.
Then we found out there’s a free surgery to fix it, and now suddenly he’s got clear 20/20 vision at almost 80! He’s got better vision than I do lol
I think similarly whenever my airways casually close up.
Waking up when the weather changes:
You’re nostrils do that as you sleep to keep the one closest to the bed/ground closed. Since people roll from side to side over the course of a night your nostrils swap which one’s closed
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.
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.

My biggest pet peeve in internet is people who state something as a fact eve though they are just really confidently wrong
Is that true? I feel like it simply wasn’t an option, so people didn’t get them.
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.
