At what age does presbyopia typically begin to occur?

Presbyopia typically begins to occur after age 40, which is aligned with the answer provided. This condition is a natural part of the aging process that affects the ability of the eye to focus on close objects. As people age, the lens of the eye becomes less flexible, making it more difficult to accommodate for near vision. This gradual loss of elasticity in the lens leads to the common experience of having to hold reading material farther away to see it clearly, a hallmark of presbyopia.

While it is true that some individuals may start to notice changes in their near vision in their late 30s, the majority will experience more significant effects after reaching 40. This age range marks the onset of presbyopia for most, explaining why that particular answer is the most accurate.
