The iris is a part of the eyeball. The iris is recognizable by its circular shape. It is the iris that determines what is commonly called eye color. The iris is inseparable from the pupil
. These two bodies
work together. The iris and pupil
constrict to adjust to the different light sources, natural or artificial, that they are subjected to. Just like fingerprints, iris patterns are unique to each individual.
