How does age affect presbyopia?

As individuals age, the lens of the eye undergoes changes that commonly result in presbyopia, which is the gradual loss of the eye's ability to focus on close objects. This condition occurs primarily because the lens becomes less flexible and more rigid over time. When the lens cannot change shape as easily, it is unable to accommodate effectively for near vision, leading to difficulties with tasks like reading or other activities that require focusing on close-up objects.

This loss of flexibility is a natural part of the aging process and is influenced by factors such as changes in the proteins within the lens and the overall structure of the eye. As the elasticity diminishes, the eye's ability to shift focus from distant to near objects diminishes, making it challenging to engage in activities that require close vision.

Understanding this mechanism is essential for those working in optometry, as it informs the ways in which practitioners can assist those experiencing presbyopia with appropriate lenses or other corrective options.
