Vedclass · Answer

(A) The human eye has a limit to its accommodation power. The minimum distance at which an object can be seen clearly without strain is known as the least distance of distinct vision or the near point of the eye. For a normal adult eye,this distance is approximately $25 \ cm$. If an object is placed closer than this,the ciliary muscles cannot adjust the focal length of the eye lens sufficiently to form a sharp image on the retina,resulting in a blurred image.

Why can you not see an object clearly if it is placed very close to your eye?
