The human eye is a complex organ that allows us to see the world around us. It works like a camera, capturing light and sending images to the brain. The main parts of the eye include the cornea, lens, and retina. The cornea helps focus light, while the lens adjusts to help us see things clearly at different distances. Inside the eye, the retina contains special cells that detect light and color. These cells send signals to the brain, which interprets them as images. This amazing process enables us to enjoy the beauty of nature, read books, and recognize faces.
