Answer Details
The ability of the eye to alter the focal length of the lens, with regard to the distance of the object from the eye, is known as accommodation. This process enables us to focus on objects at different distances by changing the shape of the lens. When we look at objects that are far away, the ciliary muscles in the eye relax and the lens becomes flatter, allowing the light to be focused on the retina. Conversely, when we look at objects that are close, the ciliary muscles contract, causing the lens to become more curved and increase its refractive power, allowing us to see the object clearly. Accommodation is an important aspect of visual perception and is essential for everyday activities such as reading, driving, and using electronic devices.
