Lens with thin film microstructure and preparation method of microstructure coating

Abstract

The invention discloses a lens with a thin film microstructure and a method for preparing a microstructure coating. Sheet, the metal sheet is provided with a plurality of round holes, and a multi-layer film is plated on the metal sheet, the multi-layer film contacts the surface of the lens through the round holes of the metal sheet, and the other positions without round holes isolate the film material In contact with the lens, a microstructure is formed in the round hole of the plated metal sheet. After the plating is completed, the metal sheet is removed, and an optical film is plated on the lens to form a lens with a thin film microstructure. The region where the film microstructure is located is different from the diopter of the main lens, which enhances the adaptability of the human eye and cultivates good eye habits. The microstructure can be made on any lens made by a conventional mold to provide different diopters, and the metal sheet can be used Repeated use greatly reduces production costs.

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
