Embodiment Construction

[0023] In order to further understand the present invention, the best implementation of the optical lens vacuum evaporation method that can effectively block blue light and infrared light is as follows: figure 1 Shown in the shown embodiment (one), at least include:

[0024] The first step is to set a lens substrate 1. The aforementioned lens substrate 1 is made of glass, resin, polycarbonate (polycarbonate; PC), acrylic resin (arcylic; acrylic resin), CR39 resin, NK55 resin, MR-series Optical lenses made of resin (such as MR7 resin, MR7.4 resin, MR8 resin, MR10 resin, etc.) or titanium crystal (trivex), and the aforementioned lens substrate 1 must be pre-cut into the desired shape, such as convex lens, concave lens , Myopia lenses, hyperopia lenses, astigmatism lenses, presbyopia lenses, screen lenses or other geometric shapes of lenses, depending on the needs of use. The aforementioned lens substrate 1 can be provided with a surface to be coated 10 on one side or both sides...

Abstract

A method of vacuum evaporation coating process that effectively block blue light and infra red light on optical lenses includes five steps. Step one is to provide a lens substrate. Step two is via vacuum evaporation coating process to evaporate silicon dioxide layer on the surface of said lens substrate. Step three is to use the vacuum evaporation coating process to evaporate zirconium dioxide layer on top of the silicon dioxide layer. Step four is to repeat step two and three to coat a plurality of silicon dioxide layers and zirconium dioxide layers. Step five is to repeat step two thus forming a multilayer stacking structure. Therefore, said stacking structure can block partial blue light and infrared light on optical lenses to achieve the effect of eye protection.

Description

technical field [0001] The invention relates to a vacuum evaporation method for optical lenses that can effectively block blue light and infrared light; especially a vacuum evaporation method that alternately stacks multiple layers of silicon dioxide layers on one or both sides of a lens substrate The optical lens and its manufacturing method are combined with multi-layer zirconia layer, trititanium pentoxide layer, titanium oxide layer or a mixed material layer composed of zirconia and titanium oxide to achieve the effect of blocking blue light and infrared light. Background technique [0002] With the advancement of science and technology and the change of human living habits, electronic products and lighting equipment such as televisions, computers, tablet computers and smart phones have become indispensable necessities in the daily life of most people. The screens of the above electronic products and the light sources of lighting equipment The rays all contain blue light...
