Light is changed into sight by converting light into electrical stimuli. These electrical impulses are sent from the retina to the brain and are interpreted as images. The retina is membrane lines the inside wall of the eye which consists of 5 main cells: photoreceptors (rods & cones), horizontal cells, bipolar cells ("on" and "off" cells) which connect photoreceptors to retinal ganglion cells, amacrine cells, and ganglion cells which are the last neurons before the optic nerve (…
