How is hyperopia corrected?

• A. With convex lenses
• B. With concave lenses
• C. With cylindrical lenses
• D. With laser surgery only

Answer: (A)

Hyperopia is farsightedness due to the eye not bending light enough to bring the image onto the retina. To fix this, you increase the eye’s converging power before the light enters the eye. Convex (plus) lenses do exactly that: they bend incoming light inward, raising the total refractive power so the focal point lands on the retina. That’s why plus lenses are the standard correction for farsightedness. Concave lenses would diverge light and push the focal point further back, worsening hyperopia. Cylindrical lenses target astigmatism by correcting power in different meridians, not the general focusing error of hyperopia. Laser surgery can correct hyperopia by reshaping the cornea, but the option that says it’s the only method isn’t accurate since glasses or contacts are also used.
