Quizplus · Accepted Answer

The iris is the colored part of the eye that is responsible for regulating the amount of light that enters through the diameter of the pupil. It does this by contracting or expanding in response to changes in light levels. The cornea is the clear outer layer of the eye that covers the iris and pupil. The retina is the layer of tissue at the back of the eye that contains light-sensitive cells. The sclera is the white part of the eye that surrounds the colored part (iris).
