Quizplus · Accepted Answer

The pupil is the opening in the center of the iris that controls the amount of light entering the eye. When it is dark, the pupil will dilate (get bigger) to let more light in, and when it is bright, the pupil will constrict (get smaller) to reduce the amount of light entering the eye. This helps regulate the amount of light entering the inner areas of the eye and protects the sensitive retina from damage.
