Which one of the following statements is not true for a person suffering from hypermetropia?

Answer & Solution

Answer: (Detailed Solution Below)

Option D: A concave lens is used to correct this defect.

Detailed Solution:

The correct answer is “A concave lens is used to correct this defect.”.
Hypermetropia, also known as arsightedness or long-sightedness, is an eye condition that makes it difficult to see objects that are close up. This is because light entering the eye is focused behind the retina, rather than on it.

It is caused by a longer focal length in the eye.

Convex lenses are used to correct hypermetropia, or farsightedness.
