AP PSYCHOLOGY

Detailed explanation-1: -The change in the shape of the lens is controlled by the ciliary muscles inside the eye. Changes in contraction of the ciliary muscles alter the focal distance of the eye, causing nearer or farther images to come into focus on the retina; this process is known as accommodation. Q.

Detailed explanation-2: -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-3: -The ciliary body produces the fluid in the eye called aqueous humor. It also contains the ciliary muscle, which changes the shape of the lens when your eyes focus on a near object. This process is called accommodation.

Detailed explanation-4: -Ciliary body The contraction or relaxation of the ciliary muscles enables the lens to change its shape to focus on objects at various distances.

Detailed explanation-5: -The process of accommodation, or focusing on near objects, occurs by a concerted action of the ciliary muscle on the zonule fibers which hold the lens in place. The ciliary muscle is a ring of smooth muscle that, upon contraction, relaxes the tension on the zonular fibers and allows the lens to become more spherical.
