What is this article about?

Vision is the overarching term used to describe the culmination of a number of complex processes that allow us to perceive the world and our place within it. It involves the lens of the eye directing light at the retina, which transforms light into electrical impulses. These impulses then travel along the optic nerve and neural pathways to the visual cortex in the brain, where sensations such as depth and motion are organised and combined with prior knowledge and feature detection to create perception.
