Detailed explanation-1: -Iris regulates the amount of light entering the eye by adjusting its size. Iris is a thin membrane, which controls pupil which in turn regulates the amount of light entering the eye.
Detailed explanation-2: -Pupil: The pupil is the opening at the center of the iris through which light passes. The iris adjusts the size of the pupil to control the amount of light that enters the eye.
Detailed explanation-3: -These muscles control the size of the pupil and thus determine how much light reaches the sensory tissue of the retina. The sphincter muscle of the iris is a circular muscle that constricts the pupil in bright light, whereas the dilator muscle of the iris expands the opening when it contracts.
Detailed explanation-4: -Final answer: Part of the eye which controls the light entering is called the Iris.
