Eye color is defined by that of the iris. Anatomy of the Eye. The middle layer of the eye between the retina and the sclera.

At the center of the iris is a hole covered by the clear cornea called the pupil where light enters the eye. The photoreceptive cells of the eye where transduction of light to nervous impulses occurs are located in the retina shown in the figure below on the inner surface of the back of the eye. The iris is the area of the eye that contains the pigment which gives the eye its color.

The front visible part of the eye is made up of the whitish sclera a coloured iris and the pupil. Light projects through your pupil and. Anatomically the eye comprises two components fused into one.
