WebLens A transparent, biconvex structure in the eye that, along with the cornea, helps to refract light to be focused on the retina. By changing shape, it functions to change the focal distance of the eye so that it can focus on objects at various distances, to allow an image to be formed on the retina. This adjustment is known as accommodation. WebSep 12, 2024 · For a converging lens, a ray that passes through the focal point exits the lens parallel to the optical axis (ray 3 in part (a)).
