Some people have large pupils, and some people have small pupils. Also, pupil size changes with age — children and young adults tend to have large pupils, and seniors usually have small pupils.

This is called Marcus Gunn pupil testing, which is sometimes called the "swinging flashlight test. Pupils normally react both directly and indirectly to light stimulation. The reaction of the pupil of the eye receiving direct illumination is called the direct response; the reaction of the other pupil is called the consensual response.
