The pupil of the eye is the opening in the center of the iris that regulates the amount of light that enters the eye. It adjusts in size—dilating in low light conditions to allow more light in, and constricting in bright light to protect the retina. This dynamic response helps optimize vision across varying lighting conditions. Additionally, the pupil can also respond to emotional stimuli, reflecting changes in arousal or focus.
