The eye lens being convex in nature converges the light rays incident on it. Hence, it focuses the light falling on it on a thin layer of nerve cells called the retina. Two Ciliary muscles hold the lens within the eye-ball and it relaxes and tightens to change the focal length of the eye lens to get the clear image on the retina.
