Explanation:
Detailed explanation-1: -This ability to change focus for close-up objects is called accommodation. The crystalline lens changes shape to accommodate near or far targets. The ability of the eye to change the shape of its lens and its focus is known as accommodation.
Detailed explanation-2: -Ciliary muscles-It helps to change the curvature of eyelens and hence changes its focal length so that we can see the object clearly placed at different position.
Detailed explanation-3: -During accommodation, the ciliary muscle contracts, releasing tension on the zonular fibers at the lens equator, allowing the lens equatorial diameter to decrease, the lens thickness to increase, and the lens anterior surface to become more steeply curved.
