Answer»

Since the person suffers from Myopia, the corrective lens will be concave or diverging lens.

Given, that the person can't see objects beyond 1.2 m directly.So, in order to view the distances beyond 1.2 m, the focal length of the lens should be 1.2 m.

Power of lens = 1 / focal length (in meter)P = 1/(-1.2)P = -0.83 Diopter

Therefore the power of the lens should be - 0.83 D
