The optic nerve (purely sensory; carry afferent impulses for vision)
Oculomotor (innervates four of the extrinsic eye muscles)
Trochlear (innervates an extrinsic eye muscle that hooks through a pulley-shaped ligament in the orbit)
Abducens (innervates the muscle that turns abducts the eyeball)
vestibulocochlear nerve
A visual field test is typically performed to determine losses in peripheral vision. It involves staring at a fixed point while lights of varying intensity are shown in different areas of your peripheral vision, and you indicate when you see them. This helps to map out any blind spots or areas of reduced vision in your peripheral field.
Vision and visual perception occur in the occipital lobe of the brain.
Each eye has one nerve for vision, the optic nerve, Cranial Nerve II. Nerves are actually bundles of many nerve fibers. There are nerves that supply impulses for the muscles associated with the eyeballs so they can move are the Cranial Nerve III, Oculomotor, Cranial Nerve IV, Trochlear, and Cranial Nerve VI, the Abducens nerve.
The main nerve required would be the optic nerve (II), although you would also use the ocular motor nerve (III) to move the eyes. Other cranial nerves involved are: Trochlear nerve (IV) and Abducens nerve (VI).
The cranial nerves that have some function in vision include the optic nerve (II), which is responsible for carrying visual information from the eye to the brain, and the oculomotor nerve (III), which controls the movement of the eye muscles.
The optic nerve, or cranial nerve II, is responsible for visual functioning and carries visual information from the eyes to the brain.

audio If vision is to visual then hearing is to sound or audio.
Well you see bryan, the nerve that is right below the hair folical happens to be worth 12 cents.
Yes, the midbrain plays a role in vision by processing visual and auditory information and relaying it to higher brain regions for further processing. The superior colliculus in the midbrain helps to orient the eyes and head towards visual stimuli.
The second cranial nerve is the optic nerve.
The primary vision processing occurs in the occipital lobe located at the back of the brain. This area, known as the primary visual cortex, receives and processes visual information from the eyes to interpret the shape, color, and movement of objects in our surroundings.
The second cranial nerve is called the optic nerve. It carries visual information from the retina at the back of the eye to the visual centers in the brain, allowing us to process and interpret visual stimuli.
