The person is suffering from myopia.
P=1/f
note: before applying the formula check if the give value is in meters ..in this case we need to convert into m
so it becomes 0.6m
1/0.6 =1.67 D

-0.6 D(Diopter) will be the power of the lens.
Explanation:
In the given case, the boy is experiencing myopia as displayed by the negative signs in the spectacles' focal length.
To rectify this defect, the concave lenses with apt power will be used.
The power of the lens will be calculated using the formula;
(P) = 1 /f(in m)
= 1/-0.60
= - 0.59D or -0.6D(Diopters)
