It receives its afferent light impulses from the retina and occipital cortex.it gives efferents to the Edinger-Westphal nuclei of both sides.
The Retina
The retinais strictly sensory.
The sensory receptors for the eyes are the optic nerve and the retina. The sensory receptor for the nose are the olfactory nerves.
The organ of vision is the retina of the eye. The sensory receptors are called photoreceptors. When photoreceptors are stimulated, impulses travel within the optic nerve (CN II) to the visual (occipital) cortex of the brain for interpretation. There are two types of photoreceptors: Cones are photoreceptors for color vision and produce sharp images while the Rods are photoreceptors for night vision and produce silhouettes of images.

I am pretty sure it is the retina.The retina not only is used for focusing but also The sides of the ''retina'' are responsible for our peripheral vision. The center area, called the macula, is ''used'' for our fine central vision and color vision. Are you referring to optical nerve impulses?
Retina
The retina
The optic nerve transmits visual impulses from the retina to the brain.
It doesn't. Vision is a function of light passing through the pupil of the eye to the retina, with impulses then sent to the occipital cortex where the brain processes the information in order to allow an image to be perceived.
