Ever wonder why sometimes you see little lines or spots in your vision, especially when looking at something bright? Well, this animation by Reflective Films and Michael Mauser for TedEd gives you an explanation!
Bits of tissue, protein, or red blood cells can be suspended in the liquid inside your eye called the vitreous humor, and they drift in the humor when you move your eyes. These floaters are not to be confused with the blue field entoptic phenomenon, which is created by white blood cells moving through capillaries in your eye, which partially block red blood cells from getting through the capillary and creates quickly-moving white lights moving across your vision.
