Abstract

The invention relates to a photoinduction anti-soil anti-fog self-cleaning resin lens and a producing method therefor. The resin lens comprises a resin lens substrate, a hard film layer arranged on the resin lens substrate, a antireflection coating covered on the hard film layer. The antireflection coating includes at least five layers of the film, wherein the outmost layer film is a TiO2-x-yCxNy film and the other layers film alternatively arrange by the TiO2-xCx flim and the SiO2 film and the first layer adjacent to the hard film layer is a TiO2-xCx film. The antireflection coating of the resin lens is prepared by the reactive magnetron sputtering technology on the resin lens plated with the hard film. The carbon doping of the titanium dioxide film is realized in the magnetron sputtering process by the reactive gas. The nitrogen doping is further realized by the plasma treatment to the carbon doped titanium dioxide film at the outmost layer of the antireflection coating. The resin lens has the advantages of many functions, stable performance, simple preparation process, low manufacturing cost and long-acting anti-soil anti-fog self-cleaning and anti-wear performance.

Description

technical field

[0001] The invention relates to a resin lens, in particular to a light-induced anti-fouling, anti-fog and self-cleaning resin lens and a preparation method thereof. Background technique

[0002] Resin lenses are light in weight, strong in impact resistance, and stable in optical performance, and have been widely used at home and abroad. Resin lenses are made of organic polymer materials with low surface hardness and poor wear resistance. They need hard coating, multi-layer anti-reflection coating and top film to improve performance. Nevertheless, in the actual use process, the surface of the coated lens is still easily contaminated by tiny particles such as fog, and there are many problems such as water mist and oil adsorption. Especially when the temperature difference is large, the fog formed on the surface of the lens is difficult to quickly eliminate. It reduces the clarity of the wearer's vision and brings great inconvenience to the user. In addition, ...

Embodiment Construction

[0022] Embodiments of the present invention are now further described in conjunction with the accompanying drawings:

[0023] As shown in the figure, an embodiment of a light-induced anti-fouling, anti-fog, and self-cleaning resin lens of the present invention includes a resin lens substrate, a hard coat layer formed on the resin lens substrate, and a The anti-reflection film on the film layer, the anti-reflection film is composed of five layers of films, the first to fourth layers of films are respectively TiO 2-x C x Thin film and SiO 2 The thin films are overlapped, and the first layer close to the hard coat layer is TiO 2-x C x film, the outermost film is TiO 2-x-y C x N y film. In the anti-reflection film of this embodiment, the refractive index of the silicon dioxide film layer is 1.46, and the refractive index of the titanium dioxide film layer is 2.3. According to the empirical formula for anti-reflection film design, when the difference between the high and low...
