What bundles of nerve fibers carry visual information from the eye?

The optic nerve is the primary bundle of nerve fibers that carries visual information from the eye to the brain. It is composed of retinal ganglion cell axons, which transmit signals generated by photoreceptors in the retina. These signals are relayed to the brain's visual processing centers, primarily the lateral geniculate nucleus (LGN) of the thalamus, before being sent to the visual cortex.
