The iris is the colored part of the eye. The pupil is the dark circle in the middle of the iris. The iris causes the pupil to expand or contract depending on the amount of light in a given area.

The optic nerve, located at the back of the eye, takes the focused message and relays it to the brain where it is processed into an image.
