Question

why do things look dark after you stare at something bright (like a lightbulb)?

In: Biology

Answer 1

Are you referring that after you look at something bright, that shape stays in your sight and everytime you blink you can see it clearly and bright while the rest looks darker?
Im interested too, I always thought it had to be with the light recieving cells having some kind of memory due to their light sensitivity.
