Bob had perfect vision until he was 45, and then he needed to start wearing glasses for reading. Most likely, Bob has developed a visual problem called:
A) presbyopia, caused by the lens of the eye losing its flexibility.
B) astigmatism, caused by a gradual shrinking of the eyeball.
C) myopia, caused by a thickening of the cornea.
D) hyperopia, caused by the eyeball becoming elongated.

Question

Quizplus · Accepted Answer

Presbyopia is a natural age-related visual problem that occurs due to the lens of the eye losing its flexibility. It typically develops around age 40-50 and affects the ability to focus on close-up objects. This description fits Bob's situation of needing glasses for reading after age 45. Astigmatism, myopia, and hyperopia are all different types of refractive errors that can affect vision, but they do not necessarily develop later in life as a result of aging.
