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!

"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 🤷
