Presbyopia, a common age-related condition, develops as part of the natural aging process. The eye's crystalline lens progressively hardens and loses its elasticity. Simultaneously, the ciliary muscles, which are responsible for changing the lens's shape to focus on objects at various distances, weaken over time. This combined effect—the stiffening of the lens and the weakening of the ciliary muscles—hinders the lens's ability to properly focus light directly onto the retina for clear vision. Instead, light rays converge behind the retina, resulting in blurred vision, particularly when viewing nearby objects.
