[0002] Due to its excellent optical properties, wide application range and unique advantages, resin lenses have become an indispensable part of people's daily life. They are widely used in making myopia and hyperopia glasses to help patients correct their vision. In addition, resin lenses can also be used to make sunglasses to protect the eyes from ultraviolet rays. The existing anti-ultraviolet resin lenses are generally of single-layer structure, and an anti-ultraviolet coating is added on the surface of the resin sheet to reflect and absorb ultraviolet rays. Initially, it has a good treatment effect on ultraviolet rays, but the coating is exposed to the outside and is easily scratched during use, resulting in the fragmentation of the coating, which will affect the use effect and service life.

The anti-ultraviolet coating is arranged between two resin sheets, and the anti-ultraviolet coating will not be worn during use, with good use effect and long service life, and can effectively solve the problems in the background technique.

[0004] To achieve the above purpose, the utility model provides the following technical scheme: an anti-ultraviolet resin lens, including resin sheet one and resin sheet two;

[0005] Resin sheet one: an ultraviolet absorption layer is arranged on its upper surface;

[0006] Resin sheet two: an ultraviolet reflection film is arranged on its lower surface, and an interlayer film is arranged between the ultraviolet absorption layer and the ultraviolet reflection film. The ultraviolet absorption layer and the ultraviolet reflection film can be used to reflect and absorb ultraviolet rays, and thus have good anti-ultraviolet effect. At the same time, the ultraviolet absorption layer and the ultraviolet reflection film are arranged between two resin sheets, which can ensure that the anti-ultraviolet coating structure will not be worn during use, and thus has good use effect and long service life.

[0007] Further, an organosilicon coating is arranged on the upper surface of the resin sheet two, which has good aging resistance.

[0008] Further, an anti-scratch layer one is arranged on the upper surface of the organosilicon coating, and an anti-scratch layer two is arranged on the lower surface of the resin sheet one to improve the scratch resistance of the lens.

[0009] Further, an oil-repellent layer one is arranged on the upper surface of the anti-scratch layer one, and an oil-repellent layer two is arranged on the lower surface of the anti-scratch layer two to reduce the pollution of the lens by oil stains.

[0010] Further, the ultraviolet absorption layer is a zinc oxide ultraviolet absorption layer, which has a good absorption effect on ultraviolet rays.

[0011] Further, the ultraviolet reflection film includes a first oxide film and a second oxide film. The first oxide film is disposed on the lower surface of the second resin sheet, and the second oxide film is provided on the lower surface of the first oxide film. The lower surface of the second oxide film is fixedly connected to the upper surface of the interlayer, which has a good reflection effect on ultraviolet rays and can utilize the interference effect of light to reflect ultraviolet rays.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: The anti-ultraviolet resin lens of the present utility model has the following advantages:

[0014] Both the first anti-scratch layer and the second anti-scratch layer are diamond-like carbon film anti-scratch layers, which are transparent and strong films that can effectively prevent the lens from being scratched. The silicone coating has good weather resistance, chemical resistance and transparency, which can extend the service life of the second resin sheet and reduce the damage of ultraviolet rays. The first oxide film and the second oxide film are alternately stacked, so that ultraviolet rays of a specific wavelength can undergo divergent reflection and transmission at the interfaces of the films, thereby achieving the effect of reflecting ultraviolet rays. Then, the ultraviolet absorption layer can absorb ultraviolet rays and convert them into harmless heat energy. The ultraviolet absorption layer and the ultraviolet reflection film can be used to reflect and absorb ultraviolet rays, thereby having a good anti-ultraviolet effect. At the same time, the ultraviolet absorption layer and the ultraviolet reflection film are arranged between the two resin sheets, which can ensure that the anti-ultraviolet coating structure will not be worn during use, and thus has a good use effect and a long service life.
