The pupil of your eye changes (growing bigger and smaller) to control light entering the eye. This allows you to see in both bright and dim light. The muscles that control the size of the pupil are called sphincter pupillae and dilator pupillae. Your pupil increases in size when there is little to no light present, and decreases in size when more light becomes available.
