What vision condition is characterized by difficulty focusing on nearby objects?

The condition characterized by difficulty focusing on nearby objects is hyperopia, commonly known as farsightedness. In hyperopia, the light entering the eye is focused behind the retina rather than directly on it, making it difficult to see objects that are close up. This often results in challenges with tasks like reading or sewing, particularly in individuals who have significant hyperopia.

While astigmatism affects the eye's curvature and may cause blurred vision at all distances, and presbyopia, which generally affects older adults, specifically impacts near vision due to the loss of elasticity in the lens, hyperopia is specifically defined by the challenge of focusing on near objects. Myopia, or nearsightedness, involves difficulty seeing distant objects clearly but does not affect near vision in the same way as hyperopia. Therefore, hyperopia is the most fitting answer for the condition described.
