The contact lens market is directly dependent on the development of science. Research in this area is not completed, and therefore the number of proposals is increasing. A brief overview of the types of lenses will help you to understand the existing range. Location: Location:

Contact lens classifications are based on several parameters. When choosing this optical instrument, one should understand the difference between lenses that perform different tasks. Some of them are designed to correct the color of the eyes or to radically change the appearance, others - for the correction of vision.

Tinted, colored and carnival lenses will help you to change the natural color of your eyes. The first ones correct the shade of the iris by several tones and are usually recommended for owners of light eyes. Color models will be able to change the saturated color of very dark eyes - the paint layer enclosed inside the lens imitates the pattern of the iris and completely overlaps its real color. For those who like to experiment with appearance, we have created carnival lenses decorated with a wide variety of designs. With them, you can surprise those around you with a sudden look of orange eyes or shock the audience with cat pupils.

According to material, contact lenses are divided into two main classes: hard and soft. Hard ones appeared earlier, now their gas-permeable models (letting oxygen to the eye) are used to correct the most difficult vision problems. Soft lenses are more common. Among the varieties of which, in turn, three special groups can be distinguished - these are spherical (correction of myopia and hyperopia), toric

(astigmatism) and multifocal (presbyopia) lenses, which differ from each other in shape. Which one is right for you, can only be determined by an ophthalmologist.

An important factor that determines the wearing comfort is the period of use. A pair of so-called "traditional" lenses are worn from six months or longer. With a planned replacement, this period is reduced to several weeks or even to one day. Each pair of these disposable lenses is put on once, thrown away in the evening, and the next one in the morning. This option is considered the most convenient in terms of hygiene. True, the price of the kit may turn out to be slightly higher than that of lenses designed for several weeks. The extended wear mode allows you not to take off a pair for up to a week, flexible wearing provides the ability to leave the lenses on your eyes at night one or two times, in the daytime mode they are put on in the morning and removed in the evening.

Before you start wearing lenses, you should definitely go to an ophthalmologist. Using a special device, he will determine which correction you need. The main parameters that you will need when buying lenses are the radius of curvature (indicated by the letters BC), diameter (D) and optical power. And you can't buy lenses based on a prescription for glasses. Since the device will be directly on the eye, and not a few millimeters away from it, the number of diopters may differ.

Even if you choose carnival or tint options, the consultation with an ophthalmologist is not canceled. Find out which manufacturer makes the most comfortable lenses for the type of lens you need. This is largely determined by their moisture content and oxygen permeability. In addition, a specialist will tell and show you how to properly put on your lenses and how to care for them.

The main principle when handling lenses is absolute cleanliness. Before putting them on or off, wash your hands with soap and water and pat dry with a waffle towel. Avoid contact with cosmetics, hairspray and deodorant particles. It is best to change the storage container as often as possible, at least every two months. Continuously following these guidelines will allow you to experience exceptional comfort when wearing contact lenses.
