How Does Presbyopia Affect Vision?

At birth the lens is soft and flexible, and its shape is easily controlled by the zonules. As we age, however, the lens gradually hardensand becomes resistant to changes in shape. Since the older lens cannot change shape as easily as it once did, the eye has increasing difficulty focusing. This loss in focusing ability, or presbyopia, results in blurred or distorted vision when looking at close objects, as shown in the example below.
