Simply put, it’s related to how the light from the camera flash bounces off the eyes.
The amount of light that reaches the retina is controlled by the pupil. When light received is bright, the pupil will dilate smaller so no excessive light will come through. On the other hand, if the pupil receive dim lighting, the pupil will widen to allow as much light into the retina.
