no no no, they gets oxygen supply from the back of your eyelids mostly. otherwise you’d have to keep your eyes open when you sleep.
cute_noker@feddit.dk 17 hours ago
So that’s why we’re not supported to open our eyes under water. Our eyeballs are suffocating!

Also your immune system will attack your eyes if it knows they’re there. Eyes are weird.
Karjalan@lemmy.world 1 day ago
Well that’s just terrifying
DeathsEmbrace@lemmy.world 1 day ago
Here’s how fucked up it is imagine the only difference between having eyes and not having eyes is one tiny small area that if it breaks at any moment the immune system can “find” your eyes which is why eye damage needs to be treated right away. One tiny barrier keeps your eyes from being identified and if that breaks your worst nightmare.

That’s also why certain contact lenses can’t be worn overnight or for long periods of time because they aren’t as breathable. At least that’s what my eye doctor said when I got them.
LikeableLime@piefed.social 1 day ago
Yep and if you wear them for too long your body will grow new blood vessels to supply your oxygen-starved eyes with what they need. These new blood vessels can cover your retina and can lead to blindness.
Learned that one by sleeping in daily disposable contacts for a while and losing a significant portion of my peripheral vision.
CybranM@feddit.nu 1 day ago
Oh damn, did not know that was a risk
RejZoR@lemmy.ml 1 day ago
That’s correct. It’s generally recommended for lenses to have at least over 100 Dk/t for sleep and they need to be approved for that. Dk/t is the measured oxygen transmission through the lens material, the higher, the better. I would not recommend lenses with Dk/t of 30 and under even for daily wear as they starve eyes of oxygen. Especially since there are very affordable ones with very high Dk/t like Miru and Biofinity (around 160 iirc).

Quit using up all the oxygen.

So if you sleep for too long you go blind?
Alcoholicorn@mander.xyz 16 hours 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.

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.

Why does this article from 2019 say otherwise?
altphoto@lemmy.today 16 hours 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.
Kimjongtooill@sh.itjust.works 19 hours 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 17 hours 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.

So like … Swim goggles will suffocate my eyes? 😦
hovercat@lemmy.blahaj.zone 1 day ago
Eventually, yeah. I had an issue with contacts when I was younger as I have to wear thick toric lenses, which allow very little oxygen through. I would wear them way too long, and I was warned that continuing to do so could cause eventually cause blindness

So what you’re saying is, my eyes are also lungs?

More like a giant alveolus. But inside out. With a giant sphincter in the middle. That poops light.

Boy, after getting a notification with this reply I had a hell of a time trying to figure out what I could have possibly said to spur it
frezik@lemmy.blahaj.zone 1 day ago
Fun fact: your intestines are also lungs. Or maybe more accurately, lungs evolved from intestines. It turns out, you can oxygenate people by sticking an oxygen supply up their ass. Which is a possible treatment for people who have suffered respiratory failure.

Wtf is going on with this timeline? First we have chess masters using their anus’s to cheat. Then sticking a finger in your butt can fix abnormal heart rythms. And now we’re going to find out that numerous of our top athletes all cheat by wearing butt plugs that release oxygen into their bowles.

Makes some sense. If it can absorb nutrients, it can probably absorb gases too.

read it up on cornea wikipedia, seems to be true :o
Instead, oxygen dissolves in tears and then diffuses throughout the cornea to keep it healthy.[5] Similarly, nutrients are transported via diffusion from the tear fluid through the outside surface and the aqueous humour through the inside surface.

Some biology science magazine years ago. Googling gives mixed results. At least the upper skin cells do breathe directly.

They don’t need oxygen when I’m sleeping?
fuckwit_mcbumcrumble@lemmy.dbzer0.com 1 day ago
It is the only part of the body without a blood supply. Instead, it receives nutrients via aqueous humor (the liquid between the cornea and vitreous).
Instead, oxygen dissolves in tears and then diffuses throughout the cornea to keep it healthy.[5] Similarly, nutrients are transported via diffusion from the tear fluid through the outside surface and the aqueous humour through the inside surface.
And because that seemed lacking still and I’m too dumb to figure it out ChatGPT’s response:
The palpebral conjunctival blood vessels and the capillaries of the eyelids supply oxygen to the tear film behind closed lids. Oxygen diffuses from these vessels into the cornea.
Catoblepas@piefed.blahaj.zone 1 day ago
You have a high concentration of blood vessels on the inside of your eyelids, which are kept in contact with the cornea by tears. It doesn’t only let oxygen through, some parts of blood (like lymph and antibodies) can also travel through the tears and into your cornea.

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

They do have blood, as any ER doc could tell you.
However, they can also breathe in a manner of speaking. Enough that it’s proposed as a possible method to keep someone alive if their lungs don’t work.

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.
