Solution
The correct option is A Hypermetropia
A
person with hypermetropia can see distant objects
clearly but cannot see nearby objects distinctly. The
near point, for the person, is farther away from the
normal near point (25 cm). This defect arises
either because (i) the focal length of the eye lens is too
long, or (ii) the eyeball has become too small. This defect
can be corrected by using a convex lens of appropriate
power. Eye-glasses
with converging lenses provide the additional focussing
power required for forming the image on the retina. Thus, the correct option A.
