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
you know whats even weirder? Some dude somewhere realized that lenses were a thing, and realized that your eyes were also just a glorified lense. And that theoretically you could just put a lense over a lense to fix the bad lensing of the lense. And it fucking worked.
Natural selection my ass.
Legend has it that it started with an old drunk man that decided to hold beer bottles to his eyes.
i dont know about that one to be honest.
Would be pretty funny though.
The “traditional” story (the one that “seems most likely” because we don’t really know) is that some kids were playing with discarded warped glass at a glassmaker’s shop and ended up with a magnifying glass or rudimentary telescope. Enter the simultaneous invention of the telescope in multiple places (very likely it wasn’t any one person in particular), Galileo starts using it for scientific stuff, now they’re making lenses on purpose. Old nearsighted lensemaker looks through it, maybe some charts or a book on the table, all of a sudden they can see well. Attach to frame. Glasses.
this seems much more likely, i like this one.
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
I remember maybe a decade or more ago some enterprising gent made a glasses design with some kind of resin in the lens, so the wearer could adjust the lens thickness to fit their needs. Nobody would back his invention so he created a non-profit to fund these glasses for the developing world. I’d love to know what happened to it because its still something I care about supporting.
Wow, that is a very cool concept. I, too, would like to back this.
My eyesight went to shit from sitting at a desk and staring at a monitor all day. I wonder if my eyesight would’ve remained perfect well into adulthood without computers.
God made you that way, and she doesn’t make mistakes. Think about it.
Hail Satan
God doesn’t exist.
Then who will I blame for all of life’s problems?
He seems to have left a test foreskin on the deployment build.
That’s tamper resistant packaging. You’re supposed to remove that before use.
I’ve always found it curious that a religion that hated women so much would make a ritual out of a genital mutilation that makes men last longer.

Natural selection hasn’t really applied to humans for thousands of years. We beat nature when we created civilizations. Which is partly why some of these less than ideal genetic traits go unchecked now in the population.
Evolution and natural selection never stops, we’ve only changed what the selective pressures are.
I don’t need it to be night to realise that. I have -13 on both eyes, near-sightedness (not sure about the correct terminology in English). I see clearly for about one centimetre right by the tip of my nose, everything closer or further than that is a blurry and fuzzy mess. To use my phone without glasses I have to press it against my nose and can only see about half of the screen width clearly.
Do you have an option for eye surgery?
I did it with -8/9 R/L and they sit at -0.5/1 diopter now nine years post LASIK. Best decision I’ve ever made.
I’ve seen videos of eye surgery, no thank you I’m happy with my glasses and contact lenses
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.
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.

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