The visual system is the part of the nervous system responsible for processing visual information. It includes the eyes, which capture light, and the brain, which interprets the signals sent from the eyes. The main components of the visual system are the retina, optic nerve, and visual cortex. When light enters the eye, it is focused on the retina, where photoreceptors convert it into electrical signals. These signals travel through the optic nerve to the visual cortex in the brain, allowing us to perceive shapes, colors, and movement. This complex process enables us to understand and interact with our environment.
