Question: 1 / 400

At what age does presbyopia commonly begin to affect individuals?

Around age 30

Around age 40

Presbyopia is a condition characterized by the gradual loss of the eye's ability to focus on nearby objects, and it typically begins to affect individuals in their early to mid-40s. At this age, the lens of the eye starts to harden and loses elasticity, making it more difficult to see up close. This is a natural part of the aging process for the eye and affects nearly everyone to some degree as they age. The onset around age 40 aligns with many individuals starting to notice changes in their near vision, leading them to seek corrective lenses for tasks such as reading or working on the computer. Understanding this timeline is important for recognizing natural developmental changes in vision and for advising patients on when they might need to consider vision correction options.
