Presbyopia is described as impaired vision as a result of aging.

• A. Retinitis pigmentosa
• B. Presbyopia
• C. Astigmatism
• D. Myopia

Answer: (B)

The main idea here is how aging affects the eye’s ability to focus up close. Presbyopia happens when the eye’s lens stiffens with age and the muscles that help the lens change focus become less effective. Because of this loss of accommodation, near tasks like reading or sewing become harder, typically starting in the 40s or 50s. That description aligns with vision impairment that develops as a result of aging. Other conditions aren’t simply aging changes in focusing power: retinitis pigmentosa is a hereditary retinal disease that progressively narrows the visual field; astigmatism is a refractive error from an irregularly shaped cornea causing blur at all distances; myopia is nearsightedness where distant vision is blurred due to how the eye focuses light, not primarily due to aging.
