The nerve that carries neural impulses from the eye to the brain.

Explanation:
Light is detected by cells in the retina, which convert light into electrical signals. These signals travel along the optic nerve, a bundle of nerve fibers that carries the information from the eye to the brain for processing into vision. The retina is the light-sensitive layer, not a nerve; the iris is the colored muscle that adjusts pupil size; the lens focuses light onto the retina. The optic nerve is the correct answer because it is the nerve that transmits the neural impulses from the retina to the brain, enabling us to see.
