portion of examination that adjusts the student opening based on the magnitude of light. (So when

The modified light go through the lens of the eye. Found behind the pupil, the lens automatically
readjusts the course of the light and delivers it in to sharp concentration onto the obtaining
location at spine of the eye-- the retina.
An incredible membrane filled with photoreceptors (a.k.a. the "poles and cones"), the retina
