The lens is one of the most important components of the eye. It is transparent and consists of layers of tissue enclosed in a tough capsule. It is suspended from the ciliary muscles by the zonular fibers.
The lens helps to refract light coming through the cornea and then focuses the light as an image onto the retina. It does this by a process called accommodation, which is achieved by the contraction and relaxation of the ciliary muscle.
The lens is about half an inch in diameter and just under a quarter inch from front to back.
