Question
Hypermetropia can be corrected by using convex lens.
✓

Answer

(i) In hypermeteropia curvature of the cornea and eye lens decreases so that the converging power of the lens becomes less.
(ii) Due to the flattening of the eye-ball the distance between the lens and retina decreases.
(iii) This defect can be convected by using convex lens convages the incident rays which are further convaged by retina to get a shop image of nearby object on the retina.
