Hyperopia (far-sightedness) is corrected by:
ARemoving the cornea
BA concave lens
CA cylindrical lens
DA convex lens
Answer & Solution
Correct answer: D. A convex lens
Hyperopia, also known as far-sightedness, is a vision defect where a person can see distant objects clearly but struggles to focus on nearby objects. This occurs because the eyeball is too short or the lens lacks sufficient refractive power, causing light rays from nearby objects to converge at a point **behind the retina**.
To correct this, we must increase the converging power of the eye's optical system. A **convex lens** (converging lens) is placed in front of the eye. It bends the incoming light rays inward before they enter the eye, ensuring that after passing through the eye's natural lens, they focus perfectly **on the retina**.
Summary of corrections:
- **Hyperopia**: Convex lens (Converging)
- **Myopia**: Concave lens (Diverging)
- **Astigmatism**: Cylindrical lens
