Solution

The correct option is D Both the statements are incorrect.​

A person with myopia can see objects close to them clearly, but not far away.
  • In myopia, light rays are concentrated ahead of the retina instead of on the retina.
  • A concave lens diverges the light a little before it enters our eye in such a way that all the light rays start to concentrate onto the retina and makes clear vision possible.

Similarly, a person with hypermetropia cannot see objects close to them clearly, but can clearly see objects which are far away.
  • In hypermetropia, light rays are concentrated on the backside of the retina instead of on the retina. This happens due to the eyeball being smaller than normal.
  • A convex lens converges the light a little before it enters our eye. This allows the light rays to concentrate on the retina and makes clear vision possible.

Therefore, myopia is corrected using a concave lens, and hypermetropia is corrected using a convex lens.
Hence, both the given statements are incorrect.
