First, light passes through the cornea, a thin tissue that protects the eye and bends light to provide focus. 2. Next, light passes through the pupil, a small opening controlled by the iris. WebbThe Visual Pathway. The visual pathway consists of the retina, optic nerves, optic chiasm, optic tracts, lateral geniculate bodies, optic radiations, and visual cortex. The pathway is, effectively, part of the central nervous system because the retinae have their embryological origins in extensions of the diencephalon.
