how light effects the pupil
to the brain
1We need light to see. Light reflects off an object. If the light is bright, the pupil will contract or shrink to let less light in, if it is dark, the pupil will dilate or become larger to let more light in.
2The light is focused by the lens to form an upside down image at the dark back wall of your eye.
3This becomes electrical signals that are sent to the brain along the optic nerve.
4The brain turns this image the right way round.
