What is hyperopia?

1. A. A shorter eyeball than normal

2. B. A longer eyeball than normal

3. C. An irregularly shaped cornea

4. D. Excessive tear production

The correct answer is: A. A shorter eyeball than normal

Hyperopia, commonly known as farsightedness, is a refractive error where distant objects can be seen more clearly than objects that are near. This is because in hyperopia, the eyeball is actually shorter than normal. This causes light rays to focus behind the retina rather than directly on it, leading to blurred vision when looking at close objects. Option B is incorrect because a longer eyeball is actually associated with myopia, not hyperopia. Option C is incorrect because an irregularly shaped cornea is more commonly associated with astigmatism, not hyperopia. Option D is incorrect because excessive tear production is unrelated to hyperopia.
