Angle-adjustable orthokeratology lens polishing device

Abstract

The invention discloses an angle-adjustable orthokeratology lens polishing device. The angle-adjustable orthokeratology lens polishing device comprises a shell, a rotating mechanism, an adjusting mechanism and a polishing mechanism, wherein the rotating mechanism comprises a sealing plate, a bearing seat, a first motor and a fixing plate, the sealing plate is fixedly connected with the top surface of a base, the bearing seat is fixedly connected to the surface of the base located in the sealing plate, the top of the bearing seat is fixedly connected with the first motor, the output end of the first motor is fixedly connected with a first output gear, the first output gear is connected with a first transmission gear in a meshed mode, the first transmission gear is fixedly connected with a rotating shaft, and a fixing plate is fixedly connected to the top of the rotating shaft; the adjusting mechanism comprises a fixing block, a movable ball and a supporting plate, the fixing block is fixedly connected with the middle of the top surface of the fixing plate, and the interior of the fixing block is movably connected with the movable ball in a chimeric mode. The angle-adjustable orthokeratology lens polishing device has the beneficial effects that the angle-adjustable orthokeratology lens polishing device is reasonable and reliable in structure, and a polishing angle can be conveniently adjusted.

Description

technical field [0001] The application relates to a polishing device, in particular to an angle-adjustable orthokeratology lens polishing device. Background technique [0002] Orthokeratology lenses are glasses made of gas-permeable hard contact lens materials, which are developed on the basis of air-tight hard material PMMA. Orthokeratology lenses use the principle of reverse geometry to change the curvature of the cornea. Effectively improve vision, but still can not solve the sequelae caused by high myopia, it is an orthokeratology lens designed with a special inverse geometry, its inner surface is composed of multiple arc segments, and the lens and tear layer are unevenly distributed , The resulting hydrodynamic effect changes the geometry of the cornea, and when worn on the front of the cornea while sleeping, it gradually flattens the curvature of the cornea and shortens the eye axis, thereby effectively preventing the development of myopia.

[0002] Orthokeratology lenses are glasses made of gas-permeable hard contact lens materials, which are developed on the basis of air-tight hard material PMMA. Orthokeratology lenses use the principle of reverse geometry to change the curvature of the cornea. Effectively improve vision, but still can not solve the sequelae caused by high myopia, it is an orthokeratology lens designed with a special inverse geometry, its inner surface is composed of multiple arc segments, and the lens and tear layer are unevenly distributed , the resulting hydrodynamic effect changes the geometry of the cornea, and when worn on the front of the cornea while sleeping, it gradually flattens the curvature of the cornea and shortens the eye axis, thereby effectively preventing the development of myopia

[0003] Orthokeratology lenses are corneal contact lenses made of special materials. Orthokeratology lenses need to be placed inside the eye, so the surface of the orthokeratology lens needs to have sufficient smoothness. It is not easy to polish the lens surface during processing of orthokeratology lenses. It is not easy to adjust the angle of the lens during the polishing process, which increases the difficulty of processing
