Solution

Iris is the ring of pigmented tissue surrounding the pupil that varies in color from person to person.
The pupil is the opening in the center of the iris where light enters the eye.

Iris contracts and dilates to control the size of the pupil, which in turn controls the amount of light entering the eye.
