Problems solved by technology

[0002] The refractive index of conventional resin lenses is lower than that of ordinary glass lenses, so resin lenses with the same degree of power are thicker and slightly less aesthetically pleasing, but the market share of glass lenses is far inferior due to weak impact resistance, fragile and other fatal weaknesses. Resin lenses

Embodiment 1

[0013] A composite high-fold eyeglass lens, graphene fiber coating 1, PMMA soft film layer 2, chemically strengthened aluminum silicate glass layer 3, PMMA soft film layer 2, zirconium dioxide coating 4, and titanium dioxide arranged sequentially from the inside to the outside Coating layer 5, graphene fiber coating layer 1 and anti-fouling film 6; the chemically strengthened aluminum silicate glass layer 3 is made of "Dragontrail" glass; the thickness of the PMMA soft film layer 2 is the thickness of the chemically strengthened aluminum silicate glass layer 3 1 / 8-1 / 10. The thickness of the graphene fiber coating 1, the zirconium dioxide coating 4, and the titanium dioxide coating 5 are all less than 50nm. In this embodiment, the above-mentioned coatings are all set to 45nm. If the coating thickness is too thick, it will easily affect the transmittance and refractive index of the lens. Optical performance. The antifouling film 6 is a vacuum-plated fluoride film with a thicknes...

Abstract

The invention relates to a composite high-refractive spectacle lens. The composite high-refractive spectacle lens consists of a graphene fiber clad layer, a PMMA soft film layer, a chemical reinforcedaluminosilicate glass layer, a PMMA soft film layer, a zirconium dioxide clad layer, a titanium dioxide clad layer, a graphene fiber clad layer and an anti-fouling film which are arranged from insideto outside in sequence; the thickness of the PMMA soft film layer is 1 / 8 to 1 / 10 of the thickness of the chemical reinforced aluminosilicate glass layer; the thicknesses of the graphene fiber clad layer, the zirconium dioxide clad layer and the titanium dioxide clad layer are smaller than 50 nm respectively; and the thickness of the anti-fouling film is smaller than 0.5 microns. The spectacle lens takes glass with high pressure resistance and high strength as a substrate, the thickness of the lens can be greatly reduced under the premise of reaching same refractive index effect, and the disadvantage that the glass lens is fragile is overcome through the combination of the soft film layer and the graphene fiber layer, so that the spectacle lens has the advantages of resin lens and glass lens.

Description

Technical field [0001] The invention relates to the technical field of optical lenses, in particular to a composite high-refractive spectacle lens. Background technique [0002] The refractive index of conventional resin lenses is lower than that of ordinary glass lenses, so the resin lenses of the same power are thicker and slightly insufficient in aesthetics. However, the market share of glass lenses is far less than that of fatal weaknesses such as weak impact resistance and fragility. Resin lenses. Summary of the invention [0003] In order to solve the above technical problems and provide a glass composite lens that is thinner and less fragile than resin lenses of the same power, the present invention provides the following technical solutions: [0004] A composite high-fold eyeglass lens. Graphene fiber coating, PMMA soft film layer, chemically strengthened aluminum silicate glass layer, PMMA soft film layer, zirconium dioxide coating, titanium dioxide coating, graphene fiber...
