Problems solved by technology

[0006] Furthermore, for orthokeratology contact lenses, the inner surface (that is, the side in contact with the cornea) is usually cut by CNC machines, so the inner surface has a certain degree of smoothness, but it is still relatively smooth compared to the cornea. Rough, so it may damage the user's cornea, and the rough surface of orthokeratology contact lenses is easy to deposit protein in tears, which in turn affects the clarity and comfort of orthokeratology co

Embodiment Construction

[0044] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0045] see image 3 , a schematic diagram of the contact lens inner arc polishing device of the present invention, including a polishing main body 1 , a polishing part 2 and an abrasive cloth 3 . The polishing body 1 is a hollow columnar body. The polishing part 2 is made of rubber, nylon, tetrafluoroethylene, acetal or polyvinyl siloxane, and the hardness of the polishing part 2 is between 15-90% of that of the contact lens. And the polishing part 2 has a head 21 and a root 22, the head 21 corresponds to the inner arc shape of the contact lens, the root 22 is arranged in the hollow column of the...

Abstract

The utility model relates to a contact lens inner arc polishing device and a method. The contact lens inner arc polishing device comprises a polishing body, a polishing portion and grinding cloth. The hardness of the polishing portion is 15-90% of that of a contact lens. The polishing portion is arranged at one end of the polishing body, and the grinding cloth wraps the polishing portion; when the contact lens inner arc polishing device is used for carrying out polishing on the contact lens, the polishing portion is simultaneously abutted against various arcs of the contact lens to enable the contact lens inner arc polishing device to simultaneously carry out the polishing on the various arcs of the contact lens at a time, and polishing time is shortened.

Description

technical field [0001] The invention relates to a polishing device and method, in particular to a contact lens inner arc polishing device and method. Background technique [0002] In order to make the contact lens fit properly with the shape of the eyeball, and to enable the wearer of the contact lens to obtain a clearer image and comfort, the inner polishing step of the contact lens is very important. [0003] Existing polishing tools include a polishing machine body (usually a copper tube) with a polishing head on it, and the polishing head polishes the inner side of the contact lens to achieve the required optical curvature and clarity. [0004] However, general rigid gas-permeable contact lenses (Rigid Gas-Permeable, referred to as: RGP) are divided into rigid oxygen-permeable corrective contact lenses and rigid oxygen-permeable orthokeratology contact lenses. The inner surface of the corrective contact lenses is not a single geometric shape. Steep in the middle and gra...
