Detailed explanation-1: -Pupils change in size to control how much light enters your eye. The colorful part of your eye (iris) controls the size of your pupil with tiny muscles. In bright light, your pupils will get smaller to prevent light from entering. In the dark, pupils get larger to allow more light in.
Detailed explanation-2: -If you’re in a bright environment, the pupil will shrink in size to allow less light to enter the eye. In dark surroundings, the pupil expands to let more light in. Your pupil’s size can also change depending on whether you’re looking at nearby or far-away objects.
Detailed explanation-3: -Another word for it is myosis, or miosis. The pupil is the part of your eye that controls how much light gets in. In bright light, your pupils get smaller (constrict) to limit the amount of light that enters.
