The human eye is a complex organ that allows us to see the world around us. It consists of several parts, including the cornea, lens, and retina. Light enters the eye through the cornea, passes through the lens, and is focused onto the retina, where it is converted into electrical signals. These signals are then sent to the brain via the optic nerve, allowing us to perceive images. The eye also has protective features, such as eyelids and tears, which help keep it moist and free from debris. Overall, the human eye plays a crucial role in vision.
