Ever wonder what those silvery, star-like spots you sometimes see in you eyes are?
Those spots may look like tiny flickers of light or swarms of fireflies. Usually they last a second or two. You may see them after receiving a blow to the head, or after doing a somersault or making some other sharp head movement.
What happens is that the sudden movement increases the pressure in the blood vessels in your eyes for a few moments. That triggers the nerves of your eyes, fooling your brains into thinking you're seeing spots of light.
