Answer Details
The process by which the eyes can properly focus images of objects of various distances on the retina is called accommodation. This is achieved by the lens changing its shape to adjust the focal length, allowing light to be properly focused on the retina. When an object is far away, the lens becomes flatter, while it becomes rounder when the object is closer. This change in shape of the lens is controlled by the ciliary muscles, which contract or relax depending on the distance of the object being viewed. Therefore, accommodation is the process by which the eyes can adjust the focus of the lens to provide clear vision at different distances.
