Detailed explanation-1: -The pupil is the black opening in the middle of the colored part of your eye (iris). The pupil gets bigger or smaller in response to changes in light. Muscles in the iris control the size of the pupil.
Detailed explanation-2: -Iris: the colored part. Cornea: a clear dome over the iris. Pupil: the black circular opening in the iris that lets light in.
Detailed explanation-3: -Pupil: The pupil is the opening at the center of the iris through which light passes.
