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

My industry is full of pseudoscience and liars. I can't fault them for not knowing, and probably came off as more harsh than i intended.

I correct patients all day, and got pretty burned in the long long ago on reddit by people who "know better" patting themselves on the back and getting my factual information downvoted to oblivion.

I feel you. The internet experts are always to confident with information they have literally never fact checked. It's just based on something they head and assumptions.

Of course everyone falls on that sometimes because we can't possibly filter every single piece of information we get.

But some people start arguing back when they are corrected instead of just going to read about the subject to see which one is true and that is just so dumb
