In my years of experience, I know that the eyes are related to the nervous system in such a way that the visual information relayed to the visual cortex of the brain via means of optic nerves is converted from image impulses to the object we eventually see. I can undoubtedly posit that the optic nerve (connecting the eye to the NS) is a cable-like group of nerve fibers that connects and transmits visual information directly from the eye to the brain.

One should know that the optic nerve admits light signals from about 125 million photoreceptors, also known as rods and cones. In my experience As such, the relationship between the eyes and the nervous system is that of visual connection and stimulation, which enables we as humans to see the things we see. Beyond reasonable doubt, any form of damage to the eye or any of its information transmitting mechanism would only result in partial or total blindness because the NS won’t be fed with nor transmit the required image impulse.

Retinal nerve tissue is connected to the brain by the optic nerve. The nerve passes through a hole located in the choroid and sclera in the back of the eye. Where nerve forms, there are no photoreceptors, resulting in a blind spot known as the optical disk. The eye is one of the more intricate and imperative sensory organs in the human body. It provides the capability to see in both bright and dim light, focusing on objects both near and far.

There are three distinct layers of tissue. These include the fibrous, vascular, and nervous tunics that create the wall of the eye and surround its gel-filled center. The innermost layer of the eye is formed by the nervous tunic (retina).
