Problems solved by technology

[0003] At present, there are many kinds of lenses, such as the common TAC polarized lens, which can block harmful light 100%, so it is very popular among consumers, especially suitable for outdoor sports. However, the lens will inevitably be scratched during sports, so The degree of wear resistance of the lens is also a consideration for consumers when purchasing. Currently, the surface hardness of TAC polarized lenses on the market can only reach H, and its wear resistance is 1.5. It is easy to be scratched or broken by hard objects. , affect the user's observation effect, not only bring inconvenience to the user, but also need to be replaced frequently, increase the cost of use, and need to be improved

Embodiment Construction

[0044] Such as figure 1 As shown, in the wear-resistant lens coating method of the present invention, the lens includes a substrate 1 formed of resin or glass, and the inner and outer surfaces of the substrate 1 are sequentially provided with a first film symmetrically from the inside to the outside. Layer 2, the second film layer 3, the third film layer 4, the fourth film layer 5, the fifth film layer 6 and the sixth film layer 7; the first film layer 2 and the fifth film layer 6 are both carbon dioxide The silicon layer has a thickness of 60-90nm; the second film layer 3 and the fourth film layer 5 are trititanium pentoxide layers, and the thickness is 20-80nm; the third film layer 4 is a metal layer with a thickness of 25-40nm; the sixth film layer 7 is a high-hardness layer with a thickness of 20-40nm; when the substrate is formed by resin, the coating method specifically includes the following steps:

[0045] 1) Clean and dry the substrate;

[0046] 2) Coating the inner...

Abstract

The invention relates to an abrasion-resistant lens film coating method. The abrasion-resistant lens film coating method comprises the following steps that (1) a substrate is cleaned and dried; (2) the inner surface and outer surface of the substrate are coated with films correspondingly, specifically, both sides of the substrate are coated with first film layers, second film layers, third film layers, fourth film layers, fifth film layers and sixth film layers correspondingly. Lens is coated with a plurality of film layers, the clarity, anti-dazzling and blue light-proof performance is effectively improved, a good contribution to the visual clarity and authenticity is provided, visual fatigue can be effectively alleviated, and the arrangement of a plurality of layers of silicon dioxide layers and high hardness layers greatly improves the abrasion resistance of the lens.

Description

technical field [0001] The invention relates to the technical field of lenses, in particular to a method for coating a wear-resistant lens. Background technique [0002] With the continuous improvement of people's culture and living standards and the development of vision care work, glasses, as a simple optical device made to correct vision or protect eyes, have played an important role in people's daily life. Spectacles are usually composed of lenses and frames. From the function of lenses, it has the functions of adjusting the amount of light entering the eyes, increasing vision, protecting eye safety and clinically treating eye diseases. [0003] At present, there are many kinds of lenses, such as the common TAC polarized lens, which can block harmful light 100%, so it is very popular among consumers, especially suitable for outdoor sports. However, the lens will inevitably be scratched during exercise, so The degree of wear resistance of the lens is also a consideration...
