It is a condition in which the Pupils of Eyes become unequal in size.
Iris
The part of Eye that is colored is known as Iris. It is a circular muscle, which is just like a donut. It has an empty hole in the center, which allows the light to enter into the Eye.
Pupil
The empty hole that allows the light to come in is known as Pupil.
Normal Reaction of Pupil to Light
When a person in bright light or in outdoors, the Pupil contracts. The opposite happens, when a person comes to a dark room. The Pupil dilates to allow the light to come into the Eye.
