The crystalline 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).
