Hypermetropia can be corrected by a converging lens.
Correction of hypermetropia is given in the following diagram:
(a) In a hypermetropic eye, the image of near by object lying at normal near point N (at 25 cm) is formed behind the retina.
(b) The near point N' of hypermetropic eye is farther away from the normal near point N
(c) Correction of hypermetropia. The convex lens forms a virtual image of the object (lying at normal near point N) at the near point N" of this eye.
