Key Concepts

Presbyopia

Presbyopia is an age-related condition where the eye's ability to focus on close objects deteriorates. This occurs as the lens loses its elasticity over time, making it harder to change shape and adjust its focus for near vision tasks.

Lens

The lens is a clear, flexible structure situated behind the iris that focuses light onto the retina. With advancing age, the lens tends to harden and lose its flexibility, which is a primary factor contributing to the development of presbyopia.
