What is the condition called when the eye cannot focus at near due to lack of accommodation?

• A. Myopia
• B. Hyperopia
• C. Presbyopia
• D. Astigmatism

Answer: (C)

Presbyopia is the condition characterized by a diminished ability to focus on near objects, primarily due to the natural aging process of the eye. As people age, the lens of the eye becomes less flexible, making it more difficult to change shape and accommodate for near vision tasks such as reading or sewing. This loss of accommodation typically occurs around the age of 40 and progresses with age. In contrast, myopia refers to nearsightedness, where distant objects appear blurry while near objects are clear. Hyperopia, or farsightedness, involves difficulty focusing on close objects as well, but this is due to the eye being too short or the cornea being too flat, which isn’t specifically linked to age-related changes in accommodation. Astigmatism is caused by an irregular shape of the cornea or lens leading to distorted or blurred vision at all distances rather than specifically affecting near vision.
