What term describes a condition where the eye has difficulty focusing on near objects?

The condition where the eye has difficulty focusing on near objects is known as presbyopia. This condition typically occurs with age as the lens of the eye becomes less flexible, making it challenging to accommodate for close vision.

Hyperopia, or farsightedness, refers to difficulty focusing on distant objects because the light entering the eye focuses behind the retina. Myopia, or nearsightedness, refers to difficulty focusing on distant objects as the light focuses in front of the retina. Astigmatism is a refractive error caused by an irregular shape of the cornea or lens, leading to blurred vision at all distances rather than a specific difficulty with close vision.

In summary, presbyopia specifically describes the age-related difficulty with near vision, making it the correct term for the condition in the question.
