What is the term for the loss of the ability to see clearly at near distances?

Myopia
Astigmatism
Hyperopia
Presbyopia

The correct answer is: Presbyopia

The term for the loss of the ability to see clearly at near distances is presbyopia. This condition typically occurs as a natural part of aging, often starting in a person's 40s or 50s. As people age, the lens of the eye becomes less flexible, making it difficult to focus on close objects. This is different from other conditions like myopia, which affects distance vision, or hyperopia, where far objects can be seen more clearly than near ones. Astigmatism involves irregular curvature of the cornea or lens, affecting overall vision clarity. Presbyopia specifically addresses difficulties with near vision, making it the correct term in this context.
