Answer:
Farsightedness is more properly called hyperopia.
Hyperopia is a refractive error of the eye where distant objects can be seen clearly, but nearby objects appear blurry. In hyperopia, the eyeball is shorter than normal or the cornea is less curved, causing light to focus behind the retina instead of directly on it.
This condition makes it difficult to see objects up close, such as when reading or working on a computer. However, distant objects may still be clear.
To correct hyperopia, glasses or contact lenses with convex lenses are typically prescribed. These lenses help to focus the light directly onto the retina, allowing for clear vision at both near and far distances.
So, the correct answer is b. hyperopia.
