Answer:He is suffering from myopia. A concave lens can be used to correct this defect. Focal length is negative and is -2/11 m

Explanation:As P= 1/F(metres) Calculate F by substituting P.

You'll get a negative answer which means the lens is concave. The defect in which concave lens is used is myopia.
