Vedclass · Answer

(B) Long-sightedness,also known as $Hypermetropia$,is a defect of vision where a person can see distant objects clearly but cannot see nearby objects distinctly.This condition occurs because the light rays from a nearby object focus behind the retina.To correct this defect,a convex lens (converging lens) of suitable focal length is used.The convex lens converges the incoming light rays before they enter the eye,allowing the image to be formed exactly on the retina.
