Name the defect of vision which can be corrected by a converging lens. Show clearly by a ray diagram how the lens corrects the defect.

For the treatment of hypermetropia, convergent lenses are used.

(A) A person with hypermetropia will construct an image of a close item behind the retina.

(b) N’ is the near point of hypermetropic eye which is farther away from the normal near point N.

(c) A virtual image of the item is created at the near spot of the eye when hypermetropia is corrected with a convex lens.
