Question

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

  1. The person can see far objects distinctly.
  2. The focal length of the lens is large.
  3. The image of the close objects is focussed behind the retina.
  4. A concave lens is used to correct this defect.

Answer:

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.
