Constrictor (circular muscle) pupillae-constricts the pupil (miosis) ex during accommodation reflex. just now. Report Abuse. Radial muscles and circular muscles. When the radial muscles contract the size of the pupil is increased. When the circular muscles contract the size of the pupil is decreased. Changing the size of the pupil controls the amount of light entering the eye.
Simultaneously, the intrinsic muscles of the eye serve to focus the eye and control the amount of light entering it. Each eye is held in place by three pairs of taut, elastic muscles (extrinsic muscles) that constantly balance the pull of the others.
