Detailed explanation-1: -The process by which certain muscles (called ciliary muscles) function to change the focal length of the eyes so that the image is clearly formed on the retina is called accommodation of the eye. This will vary for near and distant objects and also for objects moving away or towards the eye.

Detailed explanation-2: -Accommodation is the ability of the lens of the eye to change shape, allowing for a change in focus from far to near. The lens, which is flexible, becomes more round to bring near objects into focus and flattens to bring distant objects into focus.

Detailed explanation-3: -The ability of the eye lens to adjust its focal length is called as power of accommodation. It helps us to see both near and distant objects clearly.

Detailed explanation-4: -For example, if one eye is closed, the open one will still adjust as necessary. If damage to the eye prevents this reflex from taking place, the field of vision will be blurry when switching between different objects. There is a quick test you and a friend can do to test your accommodation reflex.
