Instead, they first pass through a complex network of interneurons within the retina itself. It is the axons of these ganglion cells that bundle together to form the optic nerve, carrying the processed data away from the eye.
Vision Process Signals Travel to Brain
Rods are highly sensitive to light and enable vision in low-light conditions, while cones are responsible for color vision and function optimally in brighter environments. This anatomical feature ensures that the left visual field of both eyes is processed by the right hemisphere of the brain, and vice versa.
Subsequently, the lens fine-tunes the focus precisely onto the retina at the back of the eye, similar to how a camera lens projects an image onto its sensor. From the chiasm, the signals travel via the optic tracts to the lateral geniculate nucleus (LGN) of the thalamus, which acts as a critical relay station, before finally reaching the primary visual cortex in the occipital lobe.

The dorsal stream, or the "where pathway," focuses on spatial awareness and the localization of objects in space. However, vision does not end in the occipital lobe.
