The Lens

An interactive Flash diagram of the lens, and the part it plays in the human eye. The lens is a clear structure located behind the pupil, held in place by suspensory ligaments (zonules), and works with the cornea to focus light on to the retina by changing shape to bend the light—stretched by the zonules—when looking at a far-away object. Observe the reshaping of the lens by dragging the object near or far from the eye, or click through a slideshow to learn about these parts of the lens, and their specific functions.
