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.
Vision Process From Light to Perception: How We See and Interpret the World
Beyond the Primary Cortex Information flows further into association areas, where distinct streams handle different aspects of perception. It begins when photons strike the photoreceptors in the retina and ends with the brain's complex interpretation of these signals, allowing us to navigate and interact with the world seamlessly.
Interpretation and Perception Arrival at the primary visual cortex marks the beginning of higher-level processing. This anatomical feature ensures that the left visual field of both eyes is processed by the right hemisphere of the brain, and vice versa.

The iris adjusts the size of the pupil to regulate the amount of light, protecting the sensitive inner structures. This light enters the eye through the cornea, which provides most of the focusing power, and passes through the pupil.
