Impairment of vision as a result of old age is known as?

• A. Presbyopia
• B. Ectopion
• C. Esotropia
• D. Periorbital Edema

Answer: (A)

Presbyopia is the age-related loss of the eye’s ability to focus on nearby objects. As we get older, the lens of the eye becomes less flexible and the focusing muscle (ciliary body) doesn’t adjust the lens as easily, making reading small print or doing close work harder. This gradual change typically starts in the 40s or 50s and explains why many people need reading glasses. The other terms describe different eye conditions: eyelid malposition, misalignment of the eyes, or eyelid/swelling, none of which are specifically about the age-related decline in near vision.
