Why Do I Sometimes See Stars?
Every now and then, usually when I get up too fast, I see stars. What is it I am actually seeing? Is this bad for my eyes?

Dr. Garrette Liu
"Seeing stars" is a common visual complaint, but it is usually a normal and harmless occurrence. If you close your eyes and rub them, you will probably see spots and flashes of light. These images you see are called "phosphenes," an entoptic phenomenon characterized by the experience of seeing light without light actually entering the eye. Phosphenes are produced by pressure on the eyes. The pressure is translated into various patterns by the optic nerve.
