Problems solved by technology

At present, anti-fog cloth and combined spray are mostly used. This method is relatively fast and convenient, but the effective duration is short (about 4-5 days), maintenance is relatively troublesome, and the cost is relatively high. Lenses that can maintain the anti-fog effect for a long time are generally rare
Furthermore, most of the anti-fog lenses currently on the market have very low surface hardness, which is far from meeting the daily wear-resistant use standard, resulting in the loss of anti-fog performance of the lens soon

Abstract

The invention discloses a vacuum coating anti-fog lens and a preparation method thereof. An optical lens anti-reflection film group layer is arranged on the front surface of a hardened resin lens after the surface is activated through ion process treatment, and the front surface of the anti-reflection film group layer is plated with an anti-fog layer after the surface is activated through ion process treatment. Ion source bombardment and ion process treatment are performed on the front surface of the hardened layer to activate the surface to obtain a film layer with a more compact surface, namely a hardened activated layer. The anti-reflection film group layer adopts a combined film layer of SiO2, ZrO2, SiO2, ZrO2, ITO, Al2O3 and SiO2 from inside to outside in sequence. Ion source bombardment and ion process treatment are performed on the front surface of the anti-reflection film group layer to activate the surface, and finally, the anti-fog layer is prepared by resistance thermal radiation heating evaporation, and the thickness of the anti-fog layer is 10-100 nm.

Description

Technical field[0001]In the field of lens of the present invention, therefore, in particular, a vacuum coating anti-fog lens and a preparation method thereof.Background technique[0002]In daily life, when you get hot tea, the lens is easy to fog. The lens will fog when you come out from the air conditioner. The lens will fog when you walk out of the indoors from the cold outdoor. Especially in the epidemic, wear a mouthful of wearing a mouth into an essential part, while wearing a week and its easily causing the lens fog, which affects the effect of wearing, and interferes with normal sight. The fog fog is not only inconvenient to our daily lives, but also affects daily normal working environment. Once the lens is fog, it is difficult to remove the surface mist by wiper. Therefore, we need a fog resin lens to solve the problem of the fog of the lens.[0003]Due to the large temperature difference, the relative drying and cold lens encounters the relative heat and moisture of the air, t...
