Human vision is the ability to perceive the surrounding environment through light. The eyes detect light and convert it into electrical signals, which are sent to the brain for processing. This process allows us to see colors, shapes, and movements, helping us navigate and interact with the world. The human eye consists of several parts, including the cornea, lens, and retina. The retina contains photoreceptor cells called rods and cones, which are responsible for detecting light intensity and color, respectively. Together, these components enable us to experience a rich visual world.
