What is the condition called that leads to impaired vision due to aging, specifically the loss of ciliary muscle function?

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

Answer: (A)

The condition characterized by impaired vision due to aging and specifically the loss of ciliary muscle function is presbyopia. As people age, the lens of the eye becomes less flexible, and the ciliary muscles that help change the shape of the lens to focus on near objects weaken. This results in difficulty focusing on close-up tasks, such as reading or sewing. Presbyopia typically starts to affect individuals in their early to mid-40s and continues to progress with age. It is a common and natural part of the aging process in the eye. The other conditions mentioned relate to different issues. Myopia refers to nearsightedness, where distant objects appear blurry because the eye is too long. Hyperopia, or farsightedness, means close objects are hard to see, usually due to a shorter eye. Astigmatism involves an irregular shape of the cornea or lens, leading to distorted or blurred vision at all distances. None of these conditions specifically relate to the age-related loss of ciliary muscle function that defines presbyopia.
