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

. Now, the power

P = \frac{1}{f}

P = \frac{1}{1.2}

P = 0.83 D

So, the person suffers from Myopia, the corrective lens will be concave or diverging lens. Hence, the power is

0.833 D
