Optic nerve

The optic nerve is a bundle of nerve fibers that connects the eye to the brain, serving as the pathway for visual information. When light hits the retina at the back of the eye, it generates electrical signals that travel through the optic nerve. The brain then interprets these signals, allowing us to see. Think of the optic nerve as a communication cable transmitting visual data from your eye to your mind. It is vital for vision, and any damage to it can cause vision loss or impairment.
