The largest sensory nerve of the eye; carries impulses for sight from the retina to the brain. Composed of retinal nerve fibers that exit the eyeball through the optic disc, traverse the orbit, and pass through the optic foramen into the cranial cavity, where they meet fibers from the other...
Optic neuritis: The optic nerve becomes inflamed, usually due to an overactiveimmune system. The result: Pain andvision loss, typically in one eye. Pterygium: A thickened mass usually on the inner part of the white part of your eyeball. It can cover a part of the cornea and lead to vis...

Light is focused primarily by the cornea – the clear front surface of the eye, which acts like a camera lens. Theiris(colored part) of the eye functions like the diaphragm of a camera, controlling the amount of light reaching the retina by automatically adjusting the size of the pupil (...
