Why do pupils constrict?
Pupils constrict when an object is brought closer to the eyes, to help them focus properly on it. Also pupils constrict when hit by light, the brighter the light, the bigger the constriction. If an equal amount of light shines into both eyes, the degree of constriction is generally equal. However, if the light is directed primarily into one eye (i.e., with a flashlight), the pupil of that eye greatly constricts (direct reflex) while the pupil of the other eye shows a much smaller degree of constriction (consensual reflex).
