Vedclass · Answer

(D) The human eye has a limited power of accommodation. To see objects closer than $25 \,cm$,the ciliary muscles need to contract significantly to increase the curvature of the eye lens,thereby decreasing its focal length. However,the ciliary muscles have a limit to their contraction,meaning the focal length of the eye lens cannot be decreased below a certain minimum value. Consequently,the image of an object placed closer than $25 \,cm$ is formed behind the retina,resulting in a blurred image. This distance of $25 \,cm$ is known as the least distance of distinct vision.
