What is "iris"?

The iris, a thin circular structure in the eye, contains pigments that give it color and helps control the amount of light that enters the eye through the pupil. It acts like a diaphragm, expanding or contracting to adjust the size of the pupil and regulate the amount of light reaching the retina. The unique pattern and color of the iris are used for identification purposes, making each person's iris distinct and individual.
