There are three cranial nerves that control the extrinsic eye muscles: oculomotor, trochlear and abducens. The oculomotor controls 4 of the 6 extrinsic eye muscles. Which one you use would depend on exactly how you rolled your eyes.
Optic nerve (II) the ocular motor nerve (III) moves the eyes. Other cranial nerves are: Trochlear nerve (IV) and Abducens nerve (VI) which contribute to rolling the eyes.
Correct me if I'm wrong but I believe it's 3rd intercranial nerve that deals with occular systems
The main nerve required would be the optic nerve (II), although you would also use the ocular motor nerve (III) to move the eyes. Other cranial nerves involved are: Trochlear nerve (IV) and Abducens nerve (VI).
Cranial Nerve 2 is directly related to sight. it is the cranial nerve that is tested when using the Snellen Chart at the eye doctor. Cranial nerves 3,4, and 6 are also related to eyes as they control your eye movements.
Each eye has one nerve for vision, the optic nerve, Cranial Nerve II. Nerves are actually bundles of many nerve fibers. There are nerves that supply impulses for the muscles associated with the eyeballs so they can move are the Cranial Nerve III, Oculomotor, Cranial Nerve IV, Trochlear, and Cranial Nerve VI, the Abducens nerve.

Cranial nerves 3, 4, and 6.
If you are rolling your eye up it is using superior rectus muscle which is innervated by your occulomotor nerves (CN III).
Eye movement is controlled by cranial nerves III, IV, and VI (Oculomotor, Trohlear, and Abducens, respectively). CN III innervates most of the muscles of the eye and is responsible for most eye movements.
The levator palpebrae muscle is primarily responsible for opening the eyelids, it is innervated by cranial nerve 3 (occulomotor nerve). Raising the eyebrows, which will also open the eyes wider and may be what you are asking about, is done by occipitofrontalis. This muscle is innervated by cranial nerve 7 (facial nerve).

The main nerve required would be the optic nerve (II), although you would also use the ocular motor nerve (III) to move the eyes. Other cranial nerves involved are: Trochlear nerve (IV) and Abducens nerve (VI).

The third cranial nerve, the oculomotor is responsible for blinking and most other eyelid movement.
