Cornea: light first passes through the curved cornea, which begins the focusing process, transparent window at the front of the eye. Pupil: light passes through the pupil after the cornea, round window (seen as a black dot in the middle of the eye) Iris: a band of muscles that controls the size of the pupil, controlled by the brain.

If too much light is entering the eye, iris causes the pupil t constrict into a tiny opening.
