Also little known fact, balls are actually eyeballs. Back in the earlier days of evolution you could still see with them. It's also where the term 4 eyes comes from.

[-] BigBananaDealer@lemmy.world 11 points 5 days ago

its how we used to be able to tell if we wiped enough

ladies had to get a friend to help them thats why that whole women going to the bathroom together thing came from. because they dont have balls. sadly

Meanwhile I still can't breathe through my arsehole

[-] Swedneck@discuss.tchncs.de 3 points 3 days ago

skill issue

[-] cute_noker@feddit.dk 15 points 6 days ago

So if you sleep for too long you go blind?

[-] Alcoholicorn@mander.xyz 32 points 6 days ago

No, the capillaries on your eyelids supply o2.

If you fall asleep with contacts on or wear them too long, blocking the supply of O2, you will grow capillaries infront of your cornea. This is bad for vision.

[-] Jarix@lemmy.world 2 points 5 days ago

Curious, I definately forgot to take it my contacts from time to time and it isn't fun waking up in them(though being able to see probably is kinda fun until you feel the discomfort anyways). Im curious about the whole process now, I'm going to try and find out more about this, wish me luck!

[-] Alcoholicorn@mander.xyz 2 points 5 days ago

Your eyedoctor can show you the capillaries in question next time you get your script renewed.

[-] Jarix@lemmy.world 1 points 4 days ago

Oh I had laser eyes installed, but good to know about when I get older if they don't stop working as good. Thanks

[-] altphoto@lemmy.today 12 points 6 days ago

Lasic surgery first cuts the cornea leaving a little flap. The doc peals the eyeball then they shoot a laser beam in various places in a pattern to ablate the lens.

Then they put the flap back over like nothing happened, but that flat will never heal. That is why I will not be getting lasic thank you.

[-] altphoto@lemmy.today 5 points 6 days ago

Lol, they all say that, but when you read the fine print...."yes, the cornea does heal after LASIK. While the corneal flap may not fully "heal" in the sense of becoming completely indistinguishable from the surrounding tissue, it does reattach and become very stable."

It's like getting penis enlargement surgery buy then you get a warning afterwards.... It will fully heal, but just don't yank it too hard or hang from it for prolonged periods greater than half a second with a force equal or greater than 10 pounds. Levitra will also enlarge your left ear, which you should have trimmed to size every month by your local veterinarian.... WTF! No, my eyes are not little meat DSLR cameras to go mess around with. So I don't share the enthusiasm others do. I may indeed need a surgery in the future, but I'll postpone it.

[-] BussyGyatt@feddit.org 7 points 5 days ago

No, my eyes are not little meat DSLR cameras

actually that's a much more apt metaphor than you seem to be comfortable admitting

[-] altphoto@lemmy.today 1 points 5 days ago

I meant it more towards the value. Like your legs are not like a table's legs....yes both do similar things but your legs are much more singularity important to yourself than a table's legs.

[-] gens@programming.dev 10 points 6 days ago

Soooo, it's like a little scar that nobody will notice?

[-] tigeruppercut@lemmy.zip 7 points 6 days ago

This is the first I've heard of the eye flap healing being the issue with lasik. I always thought it was the fact that they can only take off just a bit of your lens with the lasers, and then if that continues to change shape as you age (which is common to normal aging eye issues), they can't go back and shoot more lasers because your lens has already become too thin from the earlier surgery.

[-] WolfLink@sh.itjust.works 4 points 5 days ago

Glasses/contacts offer better vision, no risk, and an easy solution to your eyes continuing to change.

[-] Kimjongtooill@sh.itjust.works 17 points 6 days ago

SMILE uses laproscopy, so the slit is only 3mm instead of 20mm for LASIK. Supposedly like a 3 day recovery time or maybe 2.

Also, does it really never heal?

[-] altphoto@lemmy.today 7 points 6 days ago

Hmm I gotta look into that. Yup never heals.

There's a new thing where they have been able to reshape the lens by first acidifying it, then returning it to normal after massaging it into a new shape... Rabbit eyes so far, not human... Because rabbits can't scream like...like...like they were reshaping their eyeballs with acid.

[-] oddlyqueer@lemmy.ml 20 points 6 days ago

Unfun fact: Rabbits actually can scream, I have had the misfortune of hearing it. It's not a sound you forget.

[-] altphoto@lemmy.today 4 points 6 days ago

Oh that's terrible.

[-] Kelp@lemmy.world 2 points 5 days ago

This reminds me of my families collective trauma, the summer of screaming bunnies!

We had our cat and her new litter of 3 kittens go out into our wooded acre property that was heavily populated by bunnies…was. Their first summer was “active”. We tried to save the first 12 or so but by the second week of July we just numbly listened to the cries while trying to eat dinner. Fun times. Miss those cats though, even if they were murder hobos

[-] grozzle@lemmy.zip 7 points 6 days ago* (last edited 6 days ago)

when you say lens, do you mean cornea? i thought most myopia, hyperopia, and astigmatism was caused by problems with the shape of the cornea.

ok, i looked up this treatment, and it says "animal tissue tests", not "animal tests", so i suspect the rabbits are long past the point of being bothered :|

[-] altphoto@lemmy.today 3 points 6 days ago

I think you're right.

[-] IzzyJ@lemmy.world 4 points 6 days ago

Wait, so what are the bliod vein things in the eyes if not supplying the eyes

[-] T156@lemmy.world 6 points 6 days ago

They supply the rest of the eye. It's just the transparent bit on front that doesn't get much of anything.

[-] thatradomguy@lemmy.world 3 points 6 days ago

how come when I don't blink it hurts and my eyes get red?

[-] Pazuzu@midwest.social 6 points 6 days ago

your eyes need to be both moist and oxygenated, the former usually requires blinking

[-] cute_noker@feddit.dk 6 points 6 days ago

Too much oxygen to the eyes.

Have you ever tried to breathe in a moving car?
Too much air is bad for you, dingus.
With the windows down.

[-] thatradomguy@lemmy.world 1 points 4 days ago

ok man relax, didn't mean to offend you. just asking...

Sorry, my pet fish wrote that. He is an extreme, anti-air radical terrorist.

[-] REDACTED@infosec.pub 3 points 6 days ago

It means you're stoned af and forgot to blink
