Question

Quizplus · Accepted Answer

The pupil is the opening in the front of the eye that changes size (dilates or constricts) in response to the amount of light in the environment. When there is less light, the pupil dilates to let in more light, and when there is more light, the pupil constricts to reduce the amount of light entering the eye. This process helps to regulate the amount of light entering the inner areas of the eye, such as the retina, to ensure optimal vision in different lighting conditions.
