Vision problems are the so-called scourge of the 21st century. Computers, phones, various other devices, as well as a sedentary lifestyle and a lot of stressful situations, have a huge impact on people's vision. You have to suffer with glasses, with daytime lenses, which can cause discomfort, or in general, someone resorts to laser correction. However, society does not stand still and comes up with something new for people with poor eyesight. Orthokeratological OK lenses (night lenses) are such an invention.
Content
Such optics are much tougher than ordinary, daytime ones. They need to be put on at night, and removed after sleep. In 6-8 hours, vision is practically restored to 100% for several days (from 24 to 72 hours). However, after the specified time, visual acuity decreases again and, accordingly, the procedure must be repeated again.
Night lenses slightly modify the tissues of the epithelium of the eye. It works like this: the ophthalmic device restores the correct position by pressing down on the corneal cells, shifting to the periphery. That is why vision becomes better, because with various pathologies (myopia, for example), focusing in the retina is distorted, and hard lenses “put in place” the cornea.
The rules are practically the same as those that apply to conventional optics.

Ophthalmic products that are worn not only during the day, but also at night. Moreover, they can be worn without removing them, but they do not have any healing properties compared to orthokeratological lenses. They differ both in composition, and in material, and in the rules of use, and in effect.
By themselves, night lenses are not yet so popular, not many people know about them and still use ordinary, daytime lenses.But it is much more convenient when nothing interferes during the day and does not hinder activity: you can swim in the pool, visit the sauna, and also engage in active sports. However, such optics also have contraindications: ranging from individual intolerance to lenses in the prince, ending with various pathologies. Accordingly, it is worth approaching your vision responsibly and obeying your ophthalmologist so that there are no incurable diseases in the future.
