The word optic comes from the Greek optikos, pertaining to sight. Aside from the optic nerve, the eye has a number of other components.These include the cornea, iris, pupil, lens, retina, macula, and vitreous. The cornea is the clear front window of the eye that transmits and focuses light into the eye.t can be viewed as the only visible part of the brain (or extension of it). The optic nerve is the second cranial nerve. The cranial nerve emerge from or enter the skull (the cranium), as opposed to the spinal nerves which emerge from the vertebral column.
