Question

Quizplus · Accepted Answer

Presbyopia is a common condition that typically develops in people over the age of 40. It is caused by a loss of flexibility in the lens of the eye, which makes it harder to focus on close objects. This results in difficulty seeing small print, such as when reading, and often leads to the need for reading glasses or bifocals. Astigmatism, myopia, and hyperopia are all refractive errors that can affect vision, but they are not typically associated with the onset of presbyopia.
