constricted pupils
Use when the pupil is noticeably smaller than usual relative to the iris, sometimes extremely small (almost dot-like), especially in manga form in which the iris is at times omitted. Can variously be elements of the eyes of a character in extreme fear, reacting to some shock or simply undergoing an autonomous reflex from exposure to bright light.
