Without direct contact, “from the light that enters our eyes to the complex cognitive processes that follow, we derive most of our information about what things are, where they are, and how they move from our vision” (Wade, Swanson 2013). The process of seeing is directly connected with our brain by a light-sensitive membrane in the back of the eye, called the retina. The lens of the eye focuses light on the layer of cells in retina, subsequently light is converted into neuronal signals, processed and sent to the primary and secondary visual cortex of the brain.
