I don't know but you are getting on my nerves!

Well I do know. The optic nerve is the second cranial nerve and carries information from the eyes into the brain. It does not have any control over the movement of the eyes as this comes from other nerves it only takes special sensory information on the images that the retina is receiving back to the brain to be processed.

The optic nerve contains approximately 1.2 million neurons.
