Level of Illumination and Pupil Size

In this video, we explore the relationship between illumination levels and their impact on pupil size, as well as the influence of temporal frequency on illumination. We delve into the Moon and Spencer (1944) equation, which provides insights into how varying levels of illumination affect the eye's response. Join us as we uncover the fascinating dynamics between light levels, pupil dilation, and temporal frequency.

Can the physical diameter of the size of the lens determines the actual entrance pupil in an optical system?
