The second group is eye lenses colored, which have an opaque coating. That's it they are used for cardinal change of tone. There are both corrective colored lenses and products without diopters.

Disadvantages of pigmented lenses

One of the main problems when wearing colored lenses is a deterioration in the quality of vision in dark rooms. Indeed, with the dilatation of the pupil part of it can be blocked by the lens (since the transparent portion does not change in size). Naturally, this can significantly worsen the perception of the surrounding space. Color lenses are relatively thicker, so their wearing time is reduced to several hours. Otherwise, inflammatory processes can not be avoided. Another unpleasant situation that can arise with such products - when blinking they can shift.

If the patient plans to resort to a laser vision correction and wants to model the result, then the night lenses will help him in this. However, do not forget that the effect is reversible, and in a day sight will be the same as it was. Only regular use can give the desired result for every day. Such lenses for the eyes of the reviews are good: addiction occurs about a week later, sleep does not interfere, leaving is fairly simple.

How to choose the right contact lenses

The most important rule when choosing methods of vision correction is consultation with an experienced specialist. He will check the condition of vision and select exactly those lenses that will be suitable for your eye shape. Having chosen a model, the doctor makes a fitting. Perhaps, not one pair of products will be needed, so that there is no discomfort when wearing. Then 10 minutes will have to wait. At the end of this time, the specialist re-examines the eyes, the position of the lenses on them. If they are selected correctly, then directly in the optics salon the patient himself will have to learn how to put on and remove the products. An ophthalmologist will talk about how to properly care for lenses, how often to change and what to avoid. According to the recommendations, the duration of wearing should be increased gradually. On the first day, enough to wear contact lenses 2 hours, in the second - 4, gradually bringing up to 10-12 hours. There are special lenses for sensitive eyes.
