What visual condition involves difficulty with both near and far objects?

Astigmatism is a visual condition caused by an irregular shape of the cornea or lens, which leads to blurred or distorted vision at various distances. People with astigmatism may struggle to see both near and far objects clearly because the light entering the eye does not focus evenly on the retina due to the uneven curvature. This condition can affect how objects appear, resulting in challenges with clarity in both close and distant vision.

In contrast, myopia, or nearsightedness, primarily causes difficulty seeing distant objects while allowing for relatively clear vision up close. Hyperopia, or farsightedness, usually results in clear distance vision but challenges with seeing nearby objects. Therefore, astigmatism distinctly affects vision across all distances, making it the correct answer in this context.
