Dream David Orthokeratology Lens is a kind of special rigid contact lens designed according to the corneal geometry and refractive power of myopia users, which is made of high oxygen permeability materials.
Use of orthokeratology lens
Orthokeratology mirror originated in the United States. After 50 years of development, it has been applied in 34 countries around the world. It is a kind of orthokeratology lens designed with special reverse geometry, and its inner surface is composed of several arc segments.
