What are night lenses, know not all

Most people have vision problems.And any of them wants to restore it at least partially. Technical progress has led to the almost universal development of myopia in the young population of the country due to frequent visits to the computer monitor.

This does not mean that the visual mechanismis imperfect. On the contrary, the eyes adjust to the most comfortable conditions in which they spend most of the time of the day. In other words, if there is a constant need to distinguish objects near, then the eye will adjust and will see them well enough. Well, in the distance people do not look much, so this visual situation becomes a rarity.

Our body does everything for comfort and qualitylife. In connection with the current situation, a person makes various attempts to improve his vision for the better. They consist in performing therapeutic gymnastics, wearing contact lenses or glasses.

A few years ago no one would have thought ofthat there are night lenses that can restore vision completely during sleep. Now it has become a reality. There were contact lenses designed specifically for this purpose.

They cost not cheap, about twelve thousandrubles. Their shelf life is two years. Night lenses are worn just before bedtime. They can not walk and read, only to sleep. The manufacturer claims that overnight the vision is restored to one hundred percent. This magical action lasts for the next day. And then they must be worn again for the night.

The advantages of having a night lens,are obvious. The whole day a person does without glasses. He sees perfectly and, most importantly, with their application, vision does not deteriorate with time. After all, everyone knows that glasses relax the muscles of the eye, as a result of which they atrophy. The consequence is the replacement of glasses every year with new ones, with thicker glasses. Therefore, night lenses are so popular. Reviews about them are very different. But the main drawback is that they are inaccessible everywhere and costly. Night lenses are sold only in ophthalmological clinics. The doctor determines their type. Wearing them is possible only with the condition of constant supervision at the ophthalmologist.

Many people believe that for the eyes suchInterventions are harmful, especially at night when they should fully rest. Also, some are afraid of infection. Here it is necessary to stipulate that night lenses need care and storage in a special liquid. Those who tried and appreciated the effect of lenses were satisfied with the result and consider them a miracle capable of delaying the operation for laser correction of vision, sometimes not yielding results.

The manufacturer claims that night lensesoxygen is let through, allowing the eyes to breathe. It remains to be noted that among all the obvious advantages of night lenses there is a serious drawback: thinning of the central epithelium of the eye with time by thirty percent. This, according to Russian ophthalmologists, can provoke the penetration of pathogenic bacteria in the eye. Everyone decides for himself whether to wear night lenses or refuse them in favor of surgery.
