The process that happens in the retina is absorption of
Light by Photo pigments. In the eyes
light enters through the aperture called the iris. It go through the lens of
the eye (a clear, doubly convex construct that is attached to muscles that make
it fatter or thinner in order to focus the light) and hits the retina. In the
retina there are rods and cones. The rods sense degrees of light and dark
(black and white) and the cones sense colors.
