After 40 years, women often develop age-long farsightedness or presbyopia . The disease is characterized by a decrease in the elasticity of the lens of the eye, because of which it loses its ability to quickly change its shape and provide a clear vision at any distance. When using glasses, you have to purchase several pairs, for example, for reading, everyday activities, work at the computer.
Multifocal contact lenses are the best alternative to eye correction glasses. They are arranged in such a way that one pair of lenses allows you to clearly see objects that are at different distances. Depending on the needs, there are several varieties of such adaptations.
How to choose multifocal contact lenses?
You can buy suitable lenses for correcting presbyopia only after consulting with an ophthalmologist. At the reception, the doctor will determine how many optical zones there should be to focus on disparate objects.
The selection of the correct multifocal contact lenses is carried out among the following types of devices:
- Bifocal. Variable lenses have 2 optical zones, in the lower part - for a clear view near, in the upper zone - for focusing on distant objects.
- Concentric. In such accessories, 2-3 optical zones are arranged around the circumference from the center to the periphery.
- Aspherical. These lenses are considered to be the most advanced and progressive. For the near vision, the central optical zone is intended. From it to the edges of the device, the refractive force varies gradually, which makes it possible to clearly see not only in the distance and near, but also at intermediate distances.
It is rather difficult to choose eyesight correction means, as they are of different types - traditional, planned replacement and one-day multifocal contact lenses. Moreover, the hardness of the material also matters, for example, there are silicone-hydrogel, rigid, and soft hydrophilic devices.
