The pupil allows light to enter the eye. Light enters through the pupil, passes through the lens, and is focused onto the retina. The retina is the back part of the eye that has the receptors that interpret what you see.
For clear vision, the eye requires the proper intensity of light. The pupil's purpose is to change shape to control the amount of light that enters the eye. Since the pupil is an opening, the work is actually done by the Iris, which has muscles that are used to change the opening of the pupil.
In low light conditions, your pupil will be larger to let more light in. On a sunny day, the pupil will be small.
The nervous system also controls the size of the pupil during periods of fear or excitement. The term "bedroom eyes" refers to a romantic partner being excited to see you, and their pupils become larger.
