Explanation:

When you look at something nearby, the muscle constricts, allowing the relatively elastic lens to curve and change its focusing power. Presbyopia is caused by a hardening of the lens of your eye, which occurs with aging. As your lens becomes less flexible, it can no longer change shape to focus on close-up images.
