Explanation:
The Pupil of the Eye
The pupil of the eye is the black circle in the center of the iris. The iris is the colored ring in the eye with a color and structure unique to each person. From the outside of the eye, light passes through the clear lens, then through the pupil. When the light reaches the tissues at the back of the eye, it is absorbed, making the pupil look black....
The iris contracts and dilates involuntarily and changes the size of the pupil. The whole job of the iris and pupil is to control the amount of light that gets into the eye. It's called a pupillary reflex, and you have probably noticed that a person's pupils are smaller in bright light and bigger in low light.
This is the pupil controlling the amount of light that goes through the lens of the eyes to the retina in the back of the eye. There is some inconsistency in pupil size and shape though. In younger people, pupil size is usually larger, and about 20% of the population has two pupils that aren't the same size as each other. You probably also noticed that not all pupils are round. Some animals, like cats and snakes, have slit-shaped pupils.
