Farsightedness (hyperopia) is corrected with what type of lens?

• A. Convex lens
• B. Concave lens
• C. Biconvex lens
• D. Plano lens

Answer: (A)

Farsightedness happens when the eye’s focusing power is not enough, so the image of a near object falls behind the retina. The fix is a light-converging lens, known as a convex (plus) lens. It bends incoming light toward each other before it enters the eye, increasing the eye’s total focusing power and moving the focal point onto the retina, which sharpens near and distance vision. A diverging lens would spread light apart and worsen hyperopia, while a plano lens has no additional focusing power.
