What is presbyopia?

What is presbyopia?

• A. Age-related conditions of the retina unrelated to accommodation
• B. A permanent loss of night vision
• C. Age-related loss of accommodation leading to blurry near vision
• D. Increased tear production with age

Answer: (C)

Presbyopia is the gradual, age-related decline in the eye’s ability to focus on near objects. As you age, the lens becomes stiffer and less able to change shape when the ciliary muscle contracts, so it can’t increase its refractive power enough for close vision. The result is blurry near vision and a need to hold reading material farther away or use reading glasses. This change is about the lens and accommodation system, not the retina, night vision, or tear production.
