Presbyopia occurs naturally with aging. The lens of the eye is unable to focus on objects that are close to the eyes.
Presbyopia is most likely the result of a decrease in the flexibility of the lens of the eye. Aging results in changes in the curvature and elasticity of the lens. Vision is further impaired by the loss of strength of the ciliary muscles, which bend and straighten the lens as the eye focuses on an object.
