Which term describes aging-related loss of near vision?

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

Answer: (A)

Presbyopia is the aging-related loss of near vision. As the lens becomes stiffer with age and the ciliary muscle loosens its ability to change the lens shape, the eye’s accommodation for close objects declines. That shift makes reading small print or doing close work harder and usually requires reading glasses or multifocal lenses. The other terms describe refractive errors not specifically tied to aging: hyperopia is farsightedness present when the eye is too short or the cornea too flat, causing difficulty with near tasks; myopia is nearsightedness, where distant objects are blurry; and astigmatism is irregular corneal curvature causing blurry vision at multiple distances.
