Why does presbyopia or tired eyesight occur? Can it be avoided? Can it be operated?

The lens, in the eyes of the young person, is very flexible and has great ability to deform by the action of the ciliary muscles. This deformability allows it to vary its power as a lens to focus on near or far objects. However, with age, it loses its elasticity and its ability to adapt. This is called presbyopia or tired eyesight. This phenomenon is common among all people with at least 40-45 years of age.

As of today, we do not have any method to prevent or avoid it. To solve the problem, reading glasses or bifocal contact lenses are prescribed. In addition, you can resort to surgery, for example, in cases associated with some diseases such as cataract, myopia or hyperopia. In other cases, it is possible to resort to Lasik refractive surgery procedures that offer a good short and distant vision. This is the case for treatments such as Supracor.
