The last twenty years have been characterized by rapid growth in contact vision correction. If in 1970 there were 1-2 million contact lens users in the world, then in 1986 there were already 25 million. In recent years, the number of such patients has increased to 80 million [9, 13]. However, contact lenses affect the morphology, physiology and immune response of the eye, and therefore require close attention from ophthalmologists [8, 3, 11, 10]. It is known that contact lenses have a mechanical effect on the cornea, and depending on the oxygen permeability of the lenses [Dk/t], the properties of the material, and the wearing regimen, in patients who long-term use of soft contact lenses (SCL), epithelial microcysts, stromal edema, polymegatism and polymorphism of the endothelium [5, 11,14].
