What does presbyopia primarily affect in clients?

Presbyopia primarily affects the ability to keep images in focus as they move closer. This age-related condition occurs due to the gradual loss of elasticity in the lens of the eye, making it difficult for individuals to focus on near objects, such as reading or doing close-up work. As a result, clients often find it necessary to hold reading materials further away or require reading glasses to see objects up close.

The underlying cause is the natural aging process, which affects the ciliary muscles and the lens. Normally, these structures allow the eye to adjust focus for different distances, but as they lose their flexibility over time, the focus on near objects becomes problematic. Thus, clients with presbyopia will express difficulty with activities that require near vision, which is why the ability to keep images in focus as they move closer is the primary impact of this condition.

Understanding this aspect is crucial for occupational therapy practice, as it informs interventions that may help clients adapt to changes in their vision.
