The pupil is a hole located in the centre of the iris of the eye that allows light to strike the retina. It appears black because light rays entering the pupil are either absorbed by the tissues inside the eye directly, or absorbed after diffuse reflections within the eye that mostly miss exiting the narrow pupil.
The pupil is the round opening in the middle of the iris or colored part of the eye. The pupil usually constricts or becomes smaller when exposed to light, and tends to dilate or become larger under low lighting or dark conditions. The human lens can be thought of as being similar in shape to a magnifying lens.
