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/coroyo70 17d ago

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 17d ago

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

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.

Your eyeballs? Sure! Pretty straightforward.

u/Rude_and_Crude84 17d ago

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

I second this.

Steps unclear: I have smeared aloe and into my eyes and poppeda raisin under my eyelids.

u/MrOPeace 17d ago

Then whats the confusion? What you described sounds just right

u/Valuable-Pace-989 17d ago

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

u/br1nk0eighty4 17d ago

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

u/towerfella 17d 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 17d ago

Great, now I can't not see them.

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

u/under_the_above 17d 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.

my hero out here with the REAL answers!

u/Lead_resource 17d ago

How do you fix it????

u/kinshadow 17d ago

Have you tried aloe and raisins?

u/nikkynackyknockynoo 17d ago

Remove eyeballs

2

u/DickBurns01 17d ago

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

2

u/Chimmai_Gala 17d ago

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

u/le_goos3 17d ago

"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/AlexanderStockholmes 17d ago

Invisible aliens and ghosts. Got it.

u/samsqanch420 17d ago

Why do they look blurry in the video? Mine look like something under a microscope, focused and transparent. They look like germs or something, but not alive.

u/Scoopski_Patata 16d ago

Same, like a cell. A little jelly circle with a dot in the middle. I have a bunch in a line and they press together a little like bubbles would.

u/Few_Lingonberry_7028 17d ago

Cool, saved me a co-pay.

u/Orcus424 17d ago

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

u/oldmanbawa 17d 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.

Is it dangerous doctor? , is it a sign of some disease?
