its serves the eye and it is called the "Optic Nerve".
Cranial nerve #2 - optic nerve - special sensory for vision Cranial nerve #3 - occulomotor nerve - motor for extraoccular muscles & parasympathetic to ciliary ganglion Cranial nerve #4 - trochlear nerve - motor for extraoccular muscle (superior oblique) Cranial nerve #6 - abduscens nerve - motor for extraoccular muscle (lateral rectus)

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.
Abducent nerve. Also called as abducens nerve. The sixth cranial nerve. Superior oblique muscle is supplied by trochlear nerve. All other muscles are supplied by oculomotor nerve.
The Optical nerver or the Second Cranial nerve controls and relays information absorbed through the rods and cones of the eye. Eye movements (eye muscles), however, are controlled by several other cranial nerves including the Oculomotor, Abducens, and Trochlear nerves.
This is one of the 12 cranial nerves and controls contraction of eye muscles and therefore eye movement.
Eye movement is controlled by cranial nerves III, IV, and VI (Oculomotor, Trohlear, and Abducens, respectively). CN III innervates most of the muscles of the eye and is responsible for most eye movements.
Arose from midbrain, relay at ciliary ganglion and supplies the iris and muscles of the eye.
The oculomotor nerve or the third cranial nerve, trochlear or forth cranial nerve and abducent or the sixth cranial nerve carry signal to your eye. The optic nerve carry the signal from the eye to the brain. Vestibulocochlear or the eighth cranial nerve carry the signal from your ear to the brain.
The levator palpebrae muscle is primarily responsible for opening the eyelids, it is innervated by cranial nerve 3 (occulomotor nerve). Raising the eyebrows, which will also open the eyes wider and may be what you are asking about, is done by occipitofrontalis. This muscle is innervated by cranial nerve 7 (facial nerve).
cranial nerve I: olfactory:smell cranial nerve II:optic:vision cranial nerve III: oculomotor: 4 of 6 eye muscles cranial nerve IV: trochlear: cranial nerve V: Trigeminal cranial nerve VI: Abducens cranial nerve VII: Facial cranial nerve VIII: Vestibulochlear: hearing cranial nerve IX: Grosspharnxgeal: saliva formation cranial nerve X: Vegus cranial nerve XI: Acessory Spinal: trapizious movement cranial nerve XII: Hypoglosseal: toungue movement
Cranial nerve III (CN3) is responsible for keeping the eye open. Cranial nerve VII (CN7) closes the eyelid.
