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 pupil gets wider in the dark but narrower in light. When narrow, the diameter is 2 to 4 millimeters. In the dark it will be the same at first, but will approach the maximum distance for a wide pupil 3 to 8 mm. In any human age group there is however considerable variation in maximal pupil size. For example, at the peak age of 15, the dark-adapted pupil can vary from 4 mm to 9 mm with different individuals. After 25 years of age the average pupil size decreases, though not at a steady rate.
