What Are the Functions of the Lens in the Eye?
The ability of the human eye to “see” is interdependent upon all of its parts. The purpose of the lens is to focus objects near and far to make them clear. The lens, like the lens of a camera, opens and shuts to allow light to reach the retina to focus an image. With age, the lens loses the function to refract light to bring images into focus. Disease can rob the lens of its function to work with light. Many conditions can be corrected with surgery.
