Hello, the price of orthokeratology lenses in our hospital is generally between 2000 and 8000, and the price is different according to the hospital, region, myopia, lens brand, material and design. RGP contains polymers such as silicon and fluorine, which can greatly increase the oxygen throughput, improve the oxygen permeability, ensure the firmness of the material, and has good wettability and anti-precipitation. Its effect of controlling and correcting adolescent true myopia and keratoconus has been clinically verified by ophthalmologists at home and abroad for many years and has been affirmed, and it has the reputation of "breathing contact lens". I hope it helps you.
