What is hyperopia and how does it affect vision?

Hyperopia, or long sightedness, occurs when light from near objects is focused behind the retina. This results in difficulty seeing close objects clearly, while distant objects may appear clearer.

This answer is strong because it clearly defines hyperopia and describes its impact on vision, demonstrating an understanding of the condition's physiological basis. The question tests the student's ability to explain a specific visual impairment and its effects.
