AP PSYCHOLOGY

Detailed explanation-1: -The cornea does most of the focusing.

Detailed explanation-2: -Lens: The lens is a clear part of the eye behind the iris that helps to focus light and images on the retina.

Detailed explanation-3: -The muscles that adjust the shape of the lens to accommodate objects of varying distance away are called the ciliary muscles.

Detailed explanation-4: -This process of adjusting the focus for different distances by changing the shape of the lens is called accommodation. Accommodation is the process of adjusting the lens of the eye so that you can see both near and far objects clearly.

Detailed explanation-5: -The lens focuses light through the vitreous humor, a clear gel-like substance that fills the back of the eye and supports the retina. The retina receives the image that the cornea focuses through the eye’s internal lens and transforms this image into electrical impulses that are carried by the optic nerve to the brain.
