Detailed explanation-1: -The optic nerve is critical to your vision. It’s an extension of your central nervous system, which includes your brain and spine. The optic nerve transmits electrical impulses from your eyes to your brain. Your brain processes this sensory information so that you can see.

Detailed explanation-2: -The optic nerve is a bundle of more than 1 million nerve fibers that carry visual messages. You have one connecting the back of each eye (your retina) to your brain. Damage to an optic nerve can cause vision loss. The type of vision loss and how severe it is depends on where the damage occurs.

Detailed explanation-3: -Accompanied by the ophthalmic artery, the optic nerve enters the bony skull through the optic foramen and travels within the optic canal to reach the middle cranial fossa. Located in the middle cranial fossa is the optic chiasm. The optic nerves of both eyes meet at the optic chiasm and form the optic tracts.
