Embodiment Construction

[0011] The present invention will be further described below in conjunction with the accompanying drawings.

[0012] like figure 1 As shown, a high-hardness anti-radiation and anti-ultraviolet spectacle lens includes a lens body 1, an ultraviolet absorbing layer 5 and a radiation protection film 6. The lens body 1 is a layered structure, and the layered structure includes a middle layer 2 and an upper surface layer 3 and the lower surface layer 4, the middle layer 2 is made of glass material, the upper surface layer 3 and the lower surface layer 4 are made of resin material, a layer of anti-radiation film 6 is pasted on the outside of the upper surface layer 3, and a layer of ultraviolet absorbing layer is pasted on the outside of the lower surface layer 4 5. The thickness of the lens body 1 is 0.3mm-0.4mm, and the thickness of the anti-radiation film 6 is 0.002mm.

[0013] The thickness of the upper surface layer 3 is the same as that of the lower surface layer 4 . The thic...

Abstract

The invention discloses an anti-radiation anti-ultraviolet spectacle lens with high hardness. The anti-radiation anti-ultraviolet spectacle lens comprises a lens body and is characterized by further comprising an ultraviolet ray absorption layer and an anti-radiation film, wherein the lens body is of a layered structure which comprises a middle layer, an upper surface layer and a lower surface layer; the middle layer is made of a glass material; the upper surface layer and the lower surface layer are made of a resin layer; a layer of the anti-radiation film is bonded with the outer side of the upper surface layer; a layer of the ultraviolet ray absorption layer is bonded with the outer side of the lower surface layer; the thickness of the lens body is 0.3 to 0.4 mm; and the thickness of the anti-radiation film is 0.002 mm. The anti-radiation anti-ultraviolet spectacle lens with high hardness provided by the invention has the advantages of simple structure, convenience in usage, high hardness, good wear resistance, more diversified functions and longer service life.

Description

technical field [0001] The invention relates to an spectacle lens, in particular to a radiation-proof and ultraviolet-proof spectacle lens with high hardness. Background technique [0002] The spectacle lens is the most important part of the glasses. Its quality is directly related to whether the user is comfortable to use. There are many types of lenses and materials are also very diverse. We choose different lenses according to the different functions of the glasses. The color of the lens has high and stable requirements on vision, color and distance, such as students, car drivers, surgeons, art workers, etc., should choose colorless and transparent lenses. At present, glass lenses are harder and more wear-resistant than resin lenses, while resin lenses are stronger than glass lenses, impact-resistant and not fragile. At the same time, the current lens does not have radiation protection and ultraviolet absorption capabilities, and has a single function of use, which canno...
