Question

Which of the following is used to correct short-sightedness?

विकल्प

• Convex lens

• Concave lens

• Convex mirror

• Concave mirror

Answer 1

Concave lens

Explanation:

In short-sightedness (myopia), the eye focuses light rays in front of the retina instead of exactly on it.

A concave lens is used because it diverges (spreads out) the incoming light rays just enough so they can focus perfectly on the retina to form a clear image.
