Answer:
The correct answer would be
- Concave lens for nearsightedness
- Convex lens for farsightedness
Nearsightedness or myopia is a condition in which a person can see the nearby objects clearly but is unable to see the objects present at a farther distance clearly.
It is usually caused due to elongation of the eyeball or when the lens becomes too curved.
It can be corrected by using a concave or diverging lens of appropriate power.
Farsightedness or hyperopia is a condition in which a person can see the distant objects clearly but is unable to see the nearby objects distance clearly.
It is usually caused due to shortening of the eyeball or when the lens loses its curvature.
It can be corrected by using a convex or converging lens of appropriate power.
