Many presbyopic patients, especially those who are not accustomed to wearing eyeglasses, are interested in contact lens correction of their refractive error. There are a variety of ways to correct presbyopia with contact lenses. Each of these options has advantages and disadvantages. The patient is individual priorities and visual demands can help decide which option to pursue.
The current generation of active living people over the age of 40-45 years - the so-called "baby boomers" - is very large group of populations.

The method monovision is way of presbyopia correction, when is corrected differently each eye. One is corrected for distance and one for near. This correction can be done in three different ways. The most commonly used method of correction is using single-vision contact lenses.
When it becomes a problem with presbyopia, and if the patient has good binocular vision, it is possible to offer him in one eye corrected for distance and the other eye corrected for near. This method of correction of presbyopia is called monovision.
Presbyopia is a disorder caused by physiological aging of the intraocular lens. The eye lens gradually loses its plasticity and elasticity, its core gets larger and denser, its lens fibers sclerotize, the lens gains some volume and this leads to gradual diminishment of the accommodation ability which is irreversible.
The correction and treatment of presbyopia must be handled individually. The amount of accommodation varies not only from person to person but also from eye to eye. Therefore it is necessary to prescribe the weakest lenses which are tolerable for good and comfortable vision in order to find the harmony between the processes of accommodation and convergence. In the case of correction it is necessary to respect working distance to which a person has to adapt its vision and which is very important in various professions.
