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.

I think similarly whenever my airways casually close up.

I apparently threw my glasses across the room in my sleep last night. Spent a solid 5 minutes going full on Velma mode looking for them.

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.

I can't imagine having to live with my natural sight 24/7.

I definitely would not be driving. Probably not walking much either, might not see the bus coming.

Remember, your only job as far as natural selection is concerned is to have offspring and have them survive long enough to repeat the cycle. Old people with bad eyesight just have to be able to keep the kids and grandkids alive.

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.

Some species members care for each other. Humans obviously (some anyways), even lions I think have been known to provide food when another has broken teeth or something.

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.

I like to tell my Republican father we'd both be classified legally blind and on the welfare he hates so much if optometry wasn't around. Helps put it in perspective for him how some people just "lose" the life lotto and need help to live in the same world as able-bodied folks.

That and a bunch of reasons

Yeah, I always get a warning message from zenni when I order glasses. It thinks my script is wrong cause it's such a weird one.

I know I'm half blind! Don't make me feel bad about it too!

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.

God made you that way, and she doesn’t make mistakes. Think about it.

As someone with bad sight, all my other senses are tingling. So, while blind people might've been unable to hunt, they would have made great night guards, which is a boon for social groups wary of nocturnal predators.

Not that this would be the only thing I would be selected out for...

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.
