ANATOMY

Detailed explanation-1: -The optic nerve is critical to your vision. It’s an extension of your central nervous system, which includes your brain and spine. The optic nerve transmits electrical impulses from your eyes to your brain. Your brain processes this sensory information so that you can see.

Detailed explanation-2: -The retina then sends nerve signals are sent through the back of the eye to the optic nerve. The optic nerve carries these signals to the brain, which interprets them as visual images. The portion of the brain that processes visual input and interprets the messages that the eye sends is called the visual cortex.

Detailed explanation-3: -Optic Nerve – carries the light impulses for sight from the retina to the brain. Retina – the most active area of the eye where the rods and cones are found. These receptors pick up the bits and pieces of the visual signals and transport them to the optic nerve for transmission to the brain.

Detailed explanation-4: -When light hits the retina (a light-sensitive layer of tissue at the back of the eye), special cells called photoreceptors turn the light into electrical signals. These electrical signals travel from the retina through the optic nerve to the brain. Then the brain turns the signals into the images you see.

Detailed explanation-5: -The nerve that carries messages from the retina to the brain.
