Why do you see 'little bugs or jellyfish' floating around when looking at the sky or a white wall?

It's not dirt in your eye, but shadows cast on your retina by 'microscopic floaters' inside your eye's vitreous humor! The inside of our eyeballs is filled with a transparent, jelly-like substance called the 'vitreous humor.' As we age, use 3C devices for extended periods, or develop myopia, the collagen fibers within the vitreous humor gradually degenerate and clump together, forming extremely small fibrous masses or droplet-like structures. When you look at a bright, uniform background (like a blue sky or a white wall), your pupils constrict, allowing light to pass through the eye. These tiny collagen clumps block the light and cast their own shadows onto the 'retina' at the back of your eye! So, those 'little bugs' you see are actually tiny shadows dancing inside your own eyeball!
