Presbyopia is defined as what?

• A. Decrease in ability to see objects close up
• B. Increase in near vision
• C. Color vision loss
• D. Night blindness

Answer: (A)

Presbyopia is an age-related decline in the eye’s ability to focus on close objects because the lens becomes less flexible and accommodation diminishes. As the lens hardens, the eye has a harder time increasing its refractive power for near tasks like reading, so close-up vision becomes blurry while distance vision is relatively preserved early on. This usually starts in the 40s and often requires reading glasses or multifocal lenses. The other options don’t fit: near vision doesn’t increase with presbyopia, color vision loss isn’t a normal aging change of accommodation, and night blindness points to separate issues like vitamin A deficiency or retinal/optic problems.
