ANATOMY

Detailed explanation-1: -The retina (pronounced: RET-nuh), the innermost of the three layers, lines the inside of the eyeball. The retina is a soft, light-sensitive layer of nervous system tissue. The optic nerve carries signals from the retina to the brain, which interprets them as visual images.

Detailed explanation-2: -Electrical impulses are communicated to the visual cortex of the brain by way of the optic nerve. The visual cortex makes sense of the electrical impulses, and either files the information for future reference or sends a message to a motor area for action.

Detailed explanation-3: -Along the optic tracts, areas of your brain, like the thalamus, relay the coded signals until they reach your occipital lobe. The main job of your occipital lobe is decoding the messages sent from your eyes and turning that information into forms the rest of your brain can use.
