The Human Visual System

The human visual system enables us to see and interpret the world around us. Light enters the eye through the cornea and lens, which focus it onto the retina at the back of the eye. The retina contains special cells called rods and cones that detect light and color. These cells convert light into electrical signals sent via the optic nerve to the brain, primarily the visual cortex. The brain processes these signals to recognize shapes, colors, depth, and motion, allowing us to understand and navigate our environment with remarkable accuracy and detail.
