The pupil is the opening in the center of the iris that regulates the amount of light entering the eye. When the pupil dilates (gets larger), more light can enter the eye, and when it constricts (gets smaller), less light enters the eye. The cornea is the clear outer covering of the eye that helps focus light. The lens is behind the iris and helps focus light onto the retina. The retina is the part of the eye that contains photoreceptors and sends visual information to the brain.
