Optic Nerve

We just learned about the Lens in the eye that helps focus light for us to see.

Another part of the eye is the Optic Nerve.

We learned before about the retina in the back of the eye that takes the light from the eye and turns it into signals that the brain can understand.

The retina is connected to a big long nerve called the optic nerve.

This nerve takes the signals from the retina and carries them all the way to the back of the brain, to the part of the brain called the occipital lobe where the signals from the eyes get turned into pictures for the brain to understand.
