They constrict to direct illumination (direct response) and to illumination of the opposite eye (consensual response). · normal pupil size in adults ranges from 2 to 4 millimeters in bright light and can dilate to 4 to 8 millimeters in dim conditions. Normal pupil size generally ranges from 2 to 4 millimeters (mm) in bright light and 4 to 8 mm in the dark or low light. The pupils are generally equal in size. It is generally 2 to 5 mm , with an average of about 4 mm.
