The normal size of the pupil ranges from 2.0 to 4.0 millimeters in bright light and 4.0 to 8.0 millimeters in the dark. Besides, the pupil size tends to get smaller with age.
The average pupil sizes in three different lighting conditions were found to be 3.35 in direct light, 3.86 mm in normal room lighting, and 6.42 mm in near-total darkness.
