The Optic Nerve

The optic nerve is a bundle of nerve fibers that transmits visual information from the retina—the light-sensitive layer at the back of your eye—to the brain. It acts like a communication highway, carrying signals generated by the light your eyes perceive to the brain’s visual centers, where they are processed into the images you see. The optic nerve is essential for vision, and any damage or disease affecting it can lead to vision loss or blind spots. It is a crucial part of the visual system, linking your eyes to your brain's ability to interpret what you see.
