Question

Quizplus · Accepted Answer

The pupil is a circular opening that controls the amount of light entering the eye by changing its size. When the pupil constricts or gets smaller, less light enters the eye; when the pupil dilates or gets larger, more light enters the eye. Therefore, the pupil is responsible for admitting the correct amount of light into the eyeball.
