In bright light, your pupils get smaller as they prevent light from entering your eyes. In dim lighting, your pupils get larger and allow light to enter.
Normally the size of the pupil is from 2 to 4 millimeters in bright light. In the dark, it is recorded usually 4 to 8 millimeters. The size of the pupil tends to get smaller as their age progresses.
According to the study, in people ages 16 to 34 years old, the average pupil size is found in three different conditions. The first condition is 3.35 mm indirect light, the second is 3.86 mm in normal light and the third one is 6.41 mm in complete darkness.
