what is meant by iris
Answers
The coloured part of your eye. The iris contains two groups of smooth muscles; a circular group called the sphincter pupillae, and a radial group called the dilator pupillae.of light that passes through the lens to the retina. To make the iris opaque, it is coated with the pigment melanin, in varying degrees for each of us. Melanin makes the eyes dark brown and 10,000 years ago, everyone's eyes were this colour. The iris is made of connective tissue, smooth muscle fibers, and pigments that give the iris its color. The pigments in the iris are made of melanin (the same pigment that gives skin its color) and lipochrome. The amount of pigment in the eye creates eye color.
