The optic nerve is a cranial nerve (CN II) that sends special somatic afferent (sensory) fibers to the lateral geniculate of the thalamus. Here, they synapse and continue via optic radiations to the primary visual cortex of the brain. The motor portion of the eye is controlled by cranial nerves as well only they are: Oculomotor (CN III), Trochlear (CN IV), and Abducens (CN VI); there is also some sympathetic innervation (not from cranial nerves) that cause pupillary dialation.

Which carnial nerves are purely sensory?

Actually, there are three cranial nerves that are completely sensory: Olfactory nerve, Optic nerve and the Vestibulocohlear nerve. The Optic nerve is responsible for sensory information for vision, the Olfactory nerve is responsible for sensory information coming from the nose and the Vestibulocohlear (the craziest word to spell) involves sensory information for hearing (get it?- cohlear, ear) and equilibrium.
