Which nerve carries neural impulses from the eye to the brain?

Signals start in the retina, where light is detected and converted into electrical impulses. Those impulses travel along the axons of retinal ganglion cells and bundle together to form the optic nerve. The optic nerve then carries these neural impulses from the eye toward the brain, where visual information is processed. The optic nerve is a cranial nerve and is purely sensory. The other eye structures listed—retina, choroid, and lens—are parts of the eye involved in detecting light and focusing images, but they do not transmit neural impulses to the brain as a nerve.
