OK mirror: orthokeratology (Orthok in foreign countries), which is translated into orthokeratology or orthokeratology technology in China. Orthokeratology lenses are made of breathable hard contact lens materials, commonly known as RGP glasses.

Action principle of OK lens: Through the mechanism of lens mechanical compression, eyelid massage and hydraulic pressure, the central area of cornea is gradually flattened, and the cornea in the adjacent central area is gradually steeped, thus changing the diopter of cornea and reducing myopia in a short time.

Extended data:

Features of OK mirror:

1. Orthokeratology is safe, reliable and effective in correcting myopia.

2. The application of high-tech materials, the innovation of lens design and the computerization of production and processing are the keys to the great success of orthokeratology and its wide acceptance by doctors and patients.

3. After using orthokeratology lens, the diopter of patients with mild and moderate myopia is obviously reduced, and their vision can be dramatically improved in a very short time.
