The inventions relate to medicine, more particularly to the field of ophthalmology, and even more particularly to various design embodiments of contact lenses intended for correcting eyesight. The claimed technical result is achieved by the proposed design embodiments of a contact lens for correcting eyesight, which allow, depending on the design embodiment, for eliminating the deformation of central corneal epithelial cells, for achieving and maintaining an orthokeratological effect, for creating a peripheral myopic defocus, inter alia for slowing the progression of myopia, for decreasing damage to the corneal epithelium during use, for reducing damage upon insertion and removal of a contact lens, for increasing the efficacy of vision correction and accelerating the process of vision correction, for enabling centering of the contact lens, and also for enabling a multifocal effect, and for providing nutrition to the cornea. The proposed design embodiments of a contact lens for correcting eyesight can be broadly applied in ophthalmology, as said embodiments will allow not only for correcting eyesight, but also for maintaining a level of eyesight, including during a period of preparation for surgical intervention. |
