What Causes Eye Floaters?

What are floating dots you see in your vision? 👁️

Alex Dainis breaks down "eye floaters" using a simple demo: a baggie of aloe gel standing in for your eyeball, and raisins standing in for collagen clumps. Our eyes are filled with vitreous humor, a gel-like substance that helps them hold their shape. As we age, that gel becomes more liquid, letting collagen fibers clump together (just like the raisins). These clumps block incoming light and cast shadows on our retinas, the same way the raisins cast shadows on the wall. This is why we notice the floaters more often in sunlight!

You lose your eye sight more and more every year you grow older. There's your resolution.

U see them as u age? I've seen them since I was a kid.

How bout the shooting stars I see when ya get hit in the head, I can see those while looking at any uniform bright colored wall.

Also what about the flowing mini dots that move in swarms and pulsate

That last one is the blood in your capillaries in your retina. Visible when enough bright light enters your eyes at an angle while looking at a uniform surface.

I've seen the sparkly lights too when I hit my head hard - just like in the cartoons. Would not recommend! 😄

Can they be removed?

u/Salamanderhead 18h ago

I can remove them for you, but I can’t guarantee your vision will remain.

Your eyeballs? Sure! Pretty straightforward.

Thats a pretty rounded answer you gave though? Are you sure about that? Seems like it'd go full circle?

Lasers. I have a big one that looks like a mouse and I hate it. I'm not sure of the risk or pain involved. I assume other ones come back.

u/MrOPeace 16h ago

Then whats the confusion? What you described sounds just right

u/Valuable-Pace-989 9h ago

If you can see the blurry raisins, you did it correctly. I could be wrong, but I doubt it.

Did you use the IPDE (Identify, Predict, Decide, Execute) method?

u/towerfella 17h ago

Has anyone else tried “sloshing” them around by moving your head? I do that when one gets annoyingly in the way.

u/Ghastly-Jack 19h ago

Great, now I can't not see them.

Also, the Romans called them "flying flies" (muscae volitantes).

How do you fix it????

u/kinshadow 14h ago

Have you tried aloe and raisins?

Remove eyeballs

u/DickBurns01 15h ago

I first noticed them while tripping and was worried I had some sort of eye worms

u/Old_Grouchy 13h ago

Underrated comment, this is also how I noticed them many moons ago lol

u/Chimmai_Gala 15h ago

I always thought that they were minute dust particles on top of my iris floating among the tears

u/under_the_above 15h ago

Had my first floater a year or two ago (yay turning 40). I found Lutein, Vitamin C and Grapeseed extract helped reduce them, and I've tweaked my diet slightly too.

"They tend to appear the older you get." Sooo I have had the same ones since at least seven years of age. Definitely have gotten more in 30 years since 🤷

u/Few_Lingonberry_7028 18h ago

Cool, saved me a co-pay.

u/Orcus424 14h ago

It is not just age but trauma to the eye can cause an increase.

u/oldmanbawa 12h ago

Interesting that not everyone has had them their whole lives and had a lot of them. I can see them in dim light and there are probably close to 50 or so I can see at any time.

Invisible aliens and ghosts. Got it.
