Retina of the Eye: What It Is, Function & Anatomy - Cleveland Clinic
What is the retina of the eye? The retina is a layer of cells at the back of your eyeball that converts light into nerve signals. It then sends those signals along your optic nerve to your brain.
Optic Nerve: What It Is, Function, Anatomy & Conditions - Cleveland Clinic
Your eyes are like cameras, with the retinas at the back of each eye detecting light and converting what they pick up into electrical signals. The optic nerve is like the cable that carries those signals to the computer that is your brain.
