Save. When the pupil becomes small it is said to be constricted. The process of pupil constriction is called miosis. As the body ages, the pupil becomes naturally smaller and does not open as wide in dim light. The average pupil diameter for a 30-year-old is 4.3 millimeters in the daylight and 7.0 millimeters at night.
The pupils look like round, black dots in the center of the eyes, but they are actually openings that allow light to enter the eyes. The size of the opening is controlled by the iris, the colored portion of the eye surrounding the pupil. The pupils constantly change size in response to light, to the eyeâs focusing distance, and to emotions. Normally, the pupils dilate (enlarge) in darker conditions to allow more light to enter the eye. The medical term for dilated pupils is mydriasis. Medications or other drugs can also cause the pupil to dilate, either intentionally or as a side effect. For example, eye care professionals often use eye drops that dilate the pupils in order to examine structures at the back of eye, such as the retina.
