Final answer:
Farsightedness, also known as hyperopia, is a vision problem where close objects appear blurry while distant vision remains clear.
Step-by-step explanation:
Farsightedness, also known as hyperopia, is a vision problem where close objects appear out of focus while distant vision remains unaffected. This is caused by the eye being too short, which results in images being focused behind the retina. In hyperopia, a convex lens is used to correct the focus and ensure that images fall on the retina.
