CN III (oculomotor nerve), CN IV (trochlear nerve), and CN VI (abducens nerve) are all responsible for the movement of the eyeballs. They innervate different muscles that control eye movements in different directions. None of these cranial nerves are sensory nerves and they do not send information to the primary visual cortex or occipital lobe. Also, while CN III does control the levator palpebrae superioris muscle, CN IV and VI do not have any role in eyelid movement.
