 What is Iris of The Eye ?

The iris is a thin, circular tissue that sits in front of the eye’s pupil and controls how much light enters the eye. The iris gets its name from the Greek goddess Iris, who was the messenger of the gods and was often pictured as carrying a rainbow. The word “iris” also means “ rainbow” in Greek.  The iris is made up of two main layers: the stroma and the epithelium.

Though mostly forgotten, the iris plays an important role in the human body. The iris is a thin, circular structure in the eye that surrounds the pupil and helps control how much light enters the eye. The colored part of the eye is actually the iris. The iris gets its color from pigments in the stroma, or the back layer of the iris.

Iris is a pigmented muscular tissue of the eye that controls the diameter and size of the pupil and thus the amount of light reaching the retina. The Iris is located between the cornea and the lens. It consists of two layers: The stroma, which is a thick layer of connective tissue and muscle fibers, and the pigmented epithelium, a thin pigmented layer. The pigmented epithelium is responsible for the color of the eye.
