Definition
Presbyopia is the loss of the crystalline's ability to vary its curvature to focus images placed at different distances. This is not a real disease, but a natural process related to advancing age. With aging, in fact, there is a progressive stiffening of the crystalline lens, which thus loses the power of accommodation and the ability to change shape to allow the correct focusing of nearby objects. Therefore, the main symptom of presbyopia is blurred vision closely.

Further indications
The first symptoms of presbyopia appear around the age of 40-45, and then gradually worsen over time.
Farsighted people tend to remove the text they are reading from their faces, because the characters appear blurred and split. Over the years, the point at which vision is sharp becomes progressively more and more distant. Furthermore, performing any action that requires close-up viewing for a prolonged time causes visual fatigue, sometimes accompanied by burning and redness of the eyes.
Presbyopia is diagnosed with an eye check.
For the correction of presbyopia, one can resort to the use of monofocal, bifocal glasses (with lunettes: they allow a correct vision from a distance and at only one close distance) or progressive (with a single pair of glasses, allow to see well more distances).
