I know this is a joke, but there might be an evolutionary advantage to being able to detect some light and movement when your eyes are closed.

[–] SasquatchBanana@lemmy.world 14 points 10 months ago

You detect light to know when to wake up or something is happening. Totally blind people also have the mechanism and why they know when it is morning (unless they are missing the organ). I am sure there are other reasons.

I'm now imagining falling asleep around a campfire, and there's... a shadow

Funnily enough I know how this would feel! I gave myself a very bad black eye during a K-hole which burst a vein above my eye causing my eye lid to swell.

It felt like having a very hot and 'sweaty' eye ball covered by a winter duvet. It was so uncomfortably hot I actually got a mini fan to blow air into my eye while I held up the swelling.

Thankfully it resolved itself but thick eye lids are not good.

Your eyeball getting warm. That’s was not the problem I was expecting.

Oh my eyes sweat sometimes too. It's totally not crying. It's sweating. Tough, manly eye sweating.

More of a story than I was expecting, coming to a thread about eyelids!

Thanks for passing on the knowledge

How did you give yourself the black eye? 🤔

I have thinner eye lids, as I have terrible eczema and as a kid they gave me skin destroyer cream for my eyes... This hit way way way to close to home:X

[–] BarrelAgedBoredom@lemm.ee 16 points 10 months ago

Thin em out a little more and then you'll have built in diving goggles. Like an alligator!

Ass lids? Aren't those normally called pants?

[–] Trex202@lemmy.one 3 points 10 months ago (1 children)

No, that would be an anal bum cover. I’ve spent five years of my life trying to invent an anal bum cover, failing to do so is my greatest regret.

tbf we're missing another pair of eyelids, we used to have a nictatating membrane like many other animals do but nowadays that's only visible as a vestige in the corner next to the nose.

look at reptiles, when they blink there's an extra transparent eyelid that slides in from the middle corner, before the main eyelids.

granted, this wouldn't block any more light as it's transparent, but at least it protects a bit better and lets you get gunk off the eyeball more expediently

fun fact, the eyelids have the thinnest skin of the whole body
