Question
A person with both myopic and hypermetropic eyes. This defect can be corrected by using ____.
- Cataract
- Convex lenses
- Myopia
- Bifocals
Hint:
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.
