The cornea is transparent. It is the top layer of the front of the eye. The black part of the eye is called the pupil. The pupil is actually the clear passage through the lens of the eye and appears black because there is no light coming back out of the eye cavity. The pupil changes in diameter as the iris dilates due to the volume of light present in the environment. The iris acts as a shutter to control the amount of light that reaches inside the eyeball.
