Problems solved by technology

In actual use, after the light passes through the anti-fatigue lens, the light transmitted from the central area of ​​the lens is focused on the retina, making the vision clear; while the light transmitted from the peripheral area of ​​the lens is focused behind the retina, making the vision blurred, thus Can not achieve good visual effects
Moreover, the existing anti-fatigue lenses cannot cut off and eliminate strong light, and cannot achieve a good eye protection effect.

Abstract

The invention discloses a manufacturing method of a spectacle lens with meshes. The method comprises the following steps of cutting treatment, quality inspection, cleaning, drying, surface hardness enhancing, first AR film plating, second AR film plating, convex surface film coating, laser drilling, first AF film plating, surface inspection, drilling inspection and packaging. According to the manufacturing method of the spectacle lens with the meshes, laser drilling is conducted on the lens through laser drilling equipment, the produced lens can cut off and eliminate disordered light generated by the phenomena such as reflection and interference, damage of high light to eyes is avoided, eye fatigue is relieved, a good eye protection effect is achieved, an object can be more obvious, and the visual effect is improved; by means of surface hardness enhancing, the surface hardness of a matrix of the lens is enhanced, and scratches are not likely to appear; by means of first AR film plating and second AR film plating, the light transmittance of the lens is enhanced on the two surfaces, and the visual effect is further improved.

Description

technical field [0001] The invention relates to the field of eyeglasses, in particular to a method for manufacturing an eyeglass lens with a mesh. Background technique [0002] With the continuous acceleration of the pace of life, people need to face computers, books, mobile phones, etc. for a long time, which puts a great burden on people's eyes, and the fatigue of the eyes is also increasing, and even cause eye diseases. [0003] In order to protect the eyes, more and more anti-fatigue lenses appear on the market. The existing anti-fatigue lenses usually add +50~+60 degree adjustment load on the lens based on the principle similar to the progressive lens, optimize the myopia luminosity to restore the micro-fluctuation to normal, restore the balance of the adjustment system of the glasses, and obtain the fatigue-free Function, to achieve the decompression of the eyes. In actual use, after the light passes through the anti-fatigue lens, the light transmitted from the centr...
