He should use bifocal lens because:-
Bifocal lenses are the lenses which are used for the people who suffer from both defects of vision that are hypermetropia and myopia, for those people who suffer from presbyopia or astigmatism. These lenses have two distinct powers and hence they serve two functions :- one is for distant vision and the other is for near vision. The lenses are divided into two parts. The upper part consists of concave lens which serves for distant vision at the lower part consists of convex lens which serves for near vision.
