Answer:
P = -1.67 dP
Explanation:
given,
myopic lawyer has a far point of = 60.0 cm = 0.6 m
If a person is suffering from myopia then he cannot see the farthest object clearly.
Image of far object does not form on the retina so, the image appear to be blur.
using lens formula
       
                 
                      
                                
 
                               P = -1.67 dP
