What type of lens is prescribed for hyperopia?

• A. Concave lenses
• B. Convex lenses
• C. Cylindrical lenses
• D. Aspheric lenses

Answer: (B)

Hyperopia, commonly known as farsightedness, is a condition where distant objects can be seen more clearly than nearby objects. This occurs because light entering the eye is focused behind the retina, often due to the eyeball being too short or the cornea having insufficient curvature. To correct hyperopia, convex lenses are utilized. Convex lenses are thicker in the center and thinner at the edges, which helps converge light rays before they enter the eye. By bending the light rays inward, convex lenses shift the focal point forward, allowing it to fall directly on the retina. This adjustment aids in clearer vision for nearby objects, alleviating the symptoms of hyperopia. In contrast, other lens types serve different purposes. Concave lenses are intended for myopia (nearsightedness), cylindrical lenses are used for astigmatism, and aspheric lenses can be a special design for managing distortions in vision but aren’t specifically for hyperopia. Therefore, the correct prescription for someone with hyperopia is convex lenses, which directly address the issue of light focus within the eye.
