Lens with film microstructure and microstructure coating preparation method

Abstract

The invention discloses a lens with a film microstructure and a microstructure coating preparation method. The lens comprises a main body, a hardening layer is arranged on the surface of the main bodylens; the hardened lens to be coated is formed; a metal sheet covers the outer surface; a plurality of circular holes are formed in the metal sheet; a multi-layer film is plated on the metal sheet; wherein the multi-layer film is in contact with the surface of the lens through the round holes of the metal sheet, the rest positions without the round holes isolate the film material from being in contact with the lens, a microstructure is formed in the plated round holes of the metal sheet, after plating is completed, the metal sheet is taken down, the optical film is plated on the lens, and thelens with the film microstructure is formed. The area where the film microstructure is located is different from the diopter of the main body lens, the fitness of human eyes is enhanced, the good eyeusing habit is cultivated, the microstructure can be manufactured on any lens manufactured through a conventional mold, different diopters are provided, the metal sheet can be repeatedly used, and the manufacturing cost is greatly reduced.

Description

technical field [0001] The invention relates to a method for preparing functional glasses, in particular to a method for preparing a lens with a thin film microstructure and a microstructure coating. Background technique [0002] Due to the long time of using the eyes or too close to the eyes, the eyes are overloaded, and the muscles inside and outside the eyes are in a state of tension for a long time without rest. Over time, when looking at a distance, the muscles of the eyes cannot relax and become spasm. Feel blurred in the distance and form myopia, increase the degree of glasses. Now there are functional lenses on the market that can suppress the refractive errors of myopia and hyperopia, but these functional lenses need to customize lens molds with microstructures or different diopters. Due to the variety of diopters, a large number of molds are required, which greatly increases the production cost. [0003] The existing patent "spectacle lens", application number: 20...

[0003] The existing patent "spectacle lens", application number: 201310628174.8, this patent proposes a spectacle lens, which suppresses the development of myopia by forming an image at a certain position in front of the retina through the second refractive power. Regional provision, in order to prepare this island structure, it is necessary to etch the corresponding shape on the lens mold in advance, which also requires customizing special molds. There are many degrees of lenses, so many molds need to be customized, which greatly increases the processing cost
