A lens is a transparent object designed to bend light in order to form an image. Lenses are found in cameras, microscopes, telescopes, eyeglasses, and also in the eyes of humans and other animals. A lens causes the light rays that hit it to bend, and the direction the rays bend depends on the shape of the lens.

The lens is a transparent, biconvex structure in the eye that, along with the cornea, helps to refract light to be focused on the retina. The lens, by changing shape, functions to change the focal distance of the eye so that it can focus on objects at various distances, thus allowing a sharp real image of the object of interest to be formed on the retina. This adjustment of the lens is known as accommodation (see also below). Accommodation is similar to the focusing of a photographic camera via movement of its lenses. The lens is more flat on its anterior side than on its posterior side.
