Which eye structure is the round, pigmented membrane?

Explanation:
The iris is the round, pigmented membrane that forms the colored ring around the pupil. It sits in front of the lens and behind the cornea, acting as a diaphragm that controls how much light enters the eye by constricting or dilating the pupil. The pigment gives the iris its color and helps absorb stray light. The pupil is simply the opening in the iris, not pigmented. The lens is a clear, biconvex structure behind the iris that focuses light onto the retina, and the retina is the light-sensitive layer at the back of the eye.
