The pupil is circular opening located in the center of the iris (the colored part of the eye). It controls the amount of light that enters the eye.
In bright light, muscles in the iris cause the pupil to become smaller, so that less light enter the eye, i dim light, the pupil becomes larger so that more light can enter the eye.
The pupil is an opening into the eyeball through which light reaches the retina, where cells perceive visual information which is sent to the optic nerve.
It is in the front center of the eye and appears as a black spot surrounded by the colored part (iris) of the eye. The iris controls the size of the pupil to manage the light entering the eye.
The pupil is an opening into the center of the eyeball, where the retina (visual receptor layer) is located.
The pupil is located in the front center of the eyeball, and its size (aperture) is controlled by the iris or colored part of the eye. The pupil is just behind the cornea, or lens, that focuses light on the interior surface of the eye (the retina).
The pupil is the dark circle at the center of your eye. It is surrounded by the iris, which is the colored part of your eye.
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.

There is one pupil in each eye. The pupil is the opening in the center of the iris that allows light to enter the eye. Its size can change depending on the lighting conditions to regulate the amount of light entering the eye.
The pupil is the opening in the center of the iris (the colored part of the eye) that allows light to enter the eye. By dilating or constricting, the pupil controls the amount of light reaching the retina at the back of the eye.
