Final answer:
Hyperopia, or farsightedness, is corrected using convex (converging) lenses, which adjust the focal point onto the retina for clearer near vision. Hyperopia can also be treated with contact lenses or corrected permanently with refractive surgery like LASIK.
Step-by-step explanation:
Corrective Lenses for Hyperopia
Farsightedness, or hyperopia, is a common vision problem where nearby objects appear blurry while distant objects remain clear. This condition is due to the eye being too short, causing light to focus behind the retina. To correct this condition, convex lenses are used, which are also known as converging lenses. These lenses are designed to converge light before it enters the eye, adjusting the focal point so that it falls directly on the retina, thereby sharpening close-up vision.
In addition to traditional eyeglasses with convex lenses, hyperopia can also be corrected through contact lenses with the same converging properties. For permanent correction, refractive surgeries such as LASIK reshape the cornea, effectively adjusting the eye's focusing ability. However, when discussing lenses specifically designed to correct hyperopia, they are referred to as convex corrective lenses or converging lenses.
