Step 1 : Introduction to the question " In the human body, which nerve links the eye to the brain? "
...
The optic nerve transmits visual information from the retina to the brain. The brain forms a picture using the information so that you can see things.
When light enters the eye, the cornea tries to focus it directly on the retina in order to get the clearest image. The retina senses the light and uses it to create impulses or currents. The retina sees the image upside-down and the optic nerve sends it to the brain so it turns it the right way up.
Each human optic nerve contains between 770,000 and 1.7 million nerve fibers. Damage to these fibres causes loss of vision, in most cases permanent.
The mandibular and trigeminal nerves supply both motor and sensory information to the brain, which allows you to move your jaw. The vestibulocochlear nerve connects the brain to the inner ear.
