D Correct answer
Explanation

Hypermetropia (long-sightedness) occurs when the eyeball is too short or the cornea has too little curvature, causing light to focus behind the retina instead of on it. Convex lenses are converging lenses that add optical power to bring the focal point forward onto the retina, effectively correcting the vision defect. Concave lenses would worsen the condition by diverging light further, while cylindrical lenses correct astigmatism and bifocals address presbyopia.
