Light first passes through the rod and cone cells, which detect the light and begin processing the visual signal. This signal then passes to the bipolar cells, which further refine and enhance the signal before passing it on to the ganglion cells. The ganglion cells then bundle together to form the optic nerve, which sends the visual signal to the brain for further processing. Finally, the pigmented epithelium helps to absorb any excess light and maintain the health of the retina.
