It allows us to see the world around us and to interact with it. The eye is a complex organ that is made up of many different parts. The cornea is the transparent front part of the eye. It helps to protect the eye and to focus light on the retina. The iris is the colored part of the eye. It controls the amount of light that enters the eye. The pupil is the black hole in the center of the iris. It is through the pupil that light enters the eye. The lens is a clear, transparent structure that helps to focus light on the retina. The retina is the light-sensitive tissue at the back of the eye. It converts light into electrical signals that are sent to the brain. The brain interprets these signals and allows us to see the world around us.
