Problems solved by technology

[0003] Existing orthokeratology lenses have the problem of high oxygen permeability and lens strength. In order to obtain higher oxygen permeability, existing orthokeratology lenses use lens materials with high oxygen permeability such as fluorosilicone acrylate, fluorine Although the addition of the material can increase the oxygen permeability of the material, it will reduce the mechanical strength of the material at the same time, making the lens vulnerable and easy to fall off

Abstract

The present invention discloses an orthokeratology lens for myopia treatment, the lens comprises a lens body, and the lens body comprises a central correction part for correcting a central portion ofan eyeball; a peripheral extension part for covering a peripheral portion of the eyeball; and an edge contact part for contacting the peripheral portion of the eyeball; wherein the peripheral extension part is arranged between the central correction part and the edge contact part; the central correction part is of a symmetrical structure relative to the central axis and is provided with a plurality of central area through holes penetrating through the inner side and the outer side of the central correction part, and the central area through holes are obliquely formed relative to the central axis. The orthokeratology lens for myopia treatment and the cleaning device of the orthokeratology lens have the advantages of being reasonable in structure and capable of better achieving the correction effect.

Description

technical field [0001] The present application relates to an orthokeratology lens, in particular to an orthokeratology lens for treating myopia. Background technique [0002] Orthokeratology lens is a kind of corneal contact lens similar to contact lens. It mainly changes the curvature of cornea gradually by wearing it on the cornea at night, so as to achieve the purpose of correcting myopia and helping myopia patients improve their vision. The process of wearing orthokeratology lenses to correct myopia is safe, reliable and effective, so it is widely welcomed by doctors and patients. During the wearing process of orthokeratology lenses, substances such as oil, protein, and corneal epithelial cells tend to adhere to the lens reflection. Therefore, it is necessary to clean and care for orthokeratology lenses before and after wearing them. [0003] Existing orthokeratology lenses have the problem of conflicting high oxygen permeability and lens strength. In order to obtain hi...
