Which of the following lens is used for the correction of hypermetropia?

Convex lens

Hypermetropia is also known as far-sightedness. A person with hypermetropia can see distant objects clearly but cannot see nearby objects distinctly.

This defect arises either because,

(i) the focal length of the eye lens is too long, or

(ii) the eyeball has become too small.

This defect can be corrected by using a convex lens of appropriate power.
