Seeing is the process by which the eyes perceive light and images from the environment. This occurs when light enters the eye through the cornea, passes through the pupil, and is focused by the lens onto the retina. The retina contains specialized cells that convert light into electrical signals, which are then sent to the brain for interpretation. The brain processes these signals to create visual images, allowing us to recognize shapes, colors, and movements. This ability to see is essential for navigating the world, identifying objects, and interacting with our surroundings. It plays a crucial role in daily activities and communication.
