The oculomotor nerve is the third cranial nerve responsible for controlling the movements of most of the eye muscles. It also helps regulate the size of the pupil and the shape of the lens for focusing. Damage to this nerve can lead to symptoms like double vision and difficulty moving the eye in certain directions.
Opening the eyes involves the cranial nerve called the oculomotor nerve (CN III). This nerve innervates the muscles responsible for raising the upper eyelid and controlling the pupil size.
The parasympathetic fibers of the oculomotor nerve (cranial nerve III) control the contraction of the circular smooth muscle of the iris, causing pupil constriction.
The sensory impulses of the eye are conducted by the optic nerve (cranial nerve II), while the motor impulses of the eye are conducted by the oculomotor nerve (cranial nerve III), trochlear nerve (cranial nerve IV), and abducens nerve (cranial nerve VI).
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.
The nerve carrying impulses from your brain to your eyelids would be a cranial nerve, such as the oculomotor nerve (responsible for eyelid movement), while the nerve carrying impulses to your heart would be part of the autonomic nervous system, such as the vagus nerve (regulating heart rate). Additionally, the nerve to the heart would primarily involve motor signals, while the nerve to the eyelids would involve sensory and motor signals for eyelid function.

oculomotor
The parasympathetic fibers of the oculomotor nerve (cranial nerve III) control the contraction of the circular smooth muscle of the iris, causing pupil constriction.
number III. oculomotor
Yes it is motor and parasympathetic.
Trochlear Nerve innervates Superior Oblique(extrinsic eye muscle)Oculomotor Nerve innervates Inferior Oblique, Superior Rectus, Inferior Rectus, and Medial Rectus (which are all extrinsic eye muscles) along with Ciliary Body, and the Iris (which are both intrinsic eye muscles)Abducens Nerve innervates Lateral Rectus(extrinsic eye muscle)
The cranial nerve involved in raising the eyelids is the oculomotor nerve (cranial nerve III). For focusing the lens of the eye for accommodation, the oculomotor nerve controls the ciliary muscle.
