Question

The power of lens in the spectacles of a person is $+2D$. The person suffers from :

• A. Hypermetropia
• B. Myopia
• C. Color blindness
• D. Presbyopia

Answer 1

The correct option is A Hypermetropia

As power is $+2D$, therefore focal length is $=\frac{1}{P}$

which is $+\frac{1}{2}m=+50cm$ so, focal length is positive which is for convex lens and a convex lens is used for correction of hypermetropia. So, the person is suffering from hypermetropia, hence correct option is $A$.
