Iris The circular muscles of the <b>iris</b> expand and contract the pupil. The size of the pupil determines how much light will enter the eye, so the iris effectively controls the amount of light that is passed to the retina. The iris is also responsible for eye color (blue, brown, green, hazel). See the related link below for more information on the iris.
The pupil is the opening in the center of the iris of the eye. A chief function of the pupil is to control the amount of light entering the eye. Two muscles, the sphincter and the dilator, control the size of the pupil in response to changes in light. The dilator muscle radiates out from the pupil like a star.
