Question

A person with both myopic and hypermetropic eyes. This defect can be corrected by using ____.

  1. Cataract
  2. Convex lenses
  3. Myopia
  4. Bifocals

hintHint:

Concave lens is used for myopia and convex lens for hypermetropia.

The correct answer is: Bifocals


    The correct option is d) Bifocals.
    If you suffer from farsightedness or nearsightedness, it is recommended that you wear bifocal/progressive lenses.
    A concave lens with proper focal length corrects myopia, and a convex lens with proper focal length corrects hypermetropia.
    These lenses are made by combining both lenses so that the upper part is concave, and the lower part is convex.
