There are two types of sensory receptors: rods and cones. Rods detect light, and cones detect shape.

The optic nerve
Second cranial nerve: The second cranial nerve is the optic nerve, the nerve that connects the eye to the brain and carries the impulses formed by the retina -- the nerve layer that lines the back of the eye, senses light and creates the impulses -- to the brain which interprets them as images.The cranial nerves emerge from or enter the skull (the cranium), as opposed to the spinal nerves which emerge from the vertebral column. There are twelve cranial nerves.In terms of its embryonic development, the optic nerve is a part of the central nervous system (CNS) rather than a peripheral nerve.
The optic nerve transmits visual impulses from the retina to the brain.
The optic nerve is a group of nerve fibers that function to provide vision. The optical never works by transferring electrical impulses to the brain from a part of the eyes known as the retina.
As with all nerves in the human body, the optic nerve transmits information. In this case, the optic nerve specifically transmits information from the retina of the eye to the brain for analysis and integration, resulting in the perception of "sight."
