(N/A) The power of accommodation is the ability of the human eye to adjust the focal length of its lens to focus on objects at varying distances.
When the ciliary muscles are relaxed,the eye lens becomes thin,its focal length increases,and distant objects are clearly visible.
To see nearby objects clearly,the ciliary muscles contract,making the eye lens thicker.
This contraction decreases the focal length of the eye lens,allowing the image of nearby objects to be formed clearly on the retina.
Thus,the ability of the eye to change its focal length to view both distant and nearby objects is known as the power of accommodation.
