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.
Not necessarily. If you are in very bright lighting, your pupils will constrict to limit the amount of light allowed to enter your eye. This protects the retina from damage. Likewise, in very low light levels, your pupils will dilate (enlarge) in order to allow more light into the eye and improve vision. This is a normal process.
