摘要：
1. Silicone hydrogel contact lens having a layered structural configuration and a gradient of water content from the inner to the outer part of the silicone hydrogel contact lens, including: silicone hydrogel core (or bulk material), completely covered by the outer (surface) layer of the hydrogel with a thickness of at least 0 , 1 μm, measured by atomic force microscopy over the cross section from the back to the front of the silicone hydrogel contact lens in a fully hydrated TATUS where the outer hydrogel layer is substantially free kremniyi wherein the water content in the outer layer of the hydrogel is not less than 1.2 times (or 120%) more than the water content in the silicone hydrogel bulk material in the fully hydrated sostoyanii.2. The silicone hydrogel contact lens according to claim 1, in which the outer (surface) layer of the hydrogel has a thickness of 0.1 to 20 μm, measured by atomic force microscopy along the cross section from the rear surface to the front surface of the silicone hydrogel contact lens in a fully hydrated state. 3. The silicone hydrogel contact lens according to claim 1, in which the outer (surface) layer of the hydrogel has a thickness of 0.25 to 15 μm, measured by atomic force microscopy along the cross section from the rear surface to the front surface of the silicone hydrogel contact lens in a fully hydrated state. four. The silicone hydrogel contact lens according to claim 1, wherein the outer (surface) layer of the hydrogel has a thickness of 0.5 to 12.5 μm, measured using an atomic force micro�1. Силиконовая гидрогелевая контактная линза, обладающая слоистой структурной конфигурацией и градиентом содержания воды от внутренней до наружной части силиконовой гидрогелевой контактной линзы, включающая: силиконовое гидрогелевое ядро (или объемный материал), полностью закрытое наружным (поверхностным) слоем гидрогеля, обладающим толщиной не менее 0,1 мкм, измеренной с помощью атомной силовой микроскопии по сечению от задней поверхности
