Description

Technical Field

[0001] This utility model relates to the field of coating technology, and in particular to an anti-radiation protective topcoat coating for eyeglasses. Background Technology

[0002] With the widespread use of electronic devices, especially computers, mobile phones, and tablets, people are spending significantly more time exposed to high-energy blue light emitted from electronic screens. Blue light has a wavelength range of 400nm to 500nm, and prolonged exposure can lead to eye fatigue, dryness, and even potential damage to the retina. Furthermore, ultraviolet (UV) radiation with wavelengths from 280nm to 400nm also poses a significant threat to eye health; long-term exposure may increase the risk of cataracts and macular degeneration.

[0003] To address these issues, various functional eyeglass lenses have emerged on the market, such as anti-blue light lenses, anti-UV lenses, and anti-reflective lenses. However, existing lens coating technologies often have only one function and cannot simultaneously meet multiple requirements such as anti-blue light, anti-UV, anti-reflective, and anti-fouling. In addition, some coating materials may affect the light transmittance or visual effect of the lens while achieving the function, reducing the user experience. Therefore, there is an urgent need to develop an anti-radiation protective topcoat coating for eyeglasses that can improve the light transmittance, anti-fouling performance, and durability of the lens while protecting the eyes from blue light and ultraviolet damage. Utility Model Content

[0005] This utility model is achieved by the following specific technical means:

[0006] An anti-radiation protective coating for eyeglasses includes a coating uniformly applied to the outer surface of the eyeglass lens; the coating includes an anti-blue light layer, an anti-ultraviolet (UV) layer, an anti-reflective layer, and a protective outer layer; the anti-blue light layer is located on the innermost side and uniformly applied to the outer surface of the eyeglass lens; the side of the anti-blue light layer away from the eyeglass lens is uniformly coated with an anti-ultraviolet (UV) layer; the side of the UV-protective layer away from the anti-blue light layer is uniformly coated with an anti-reflective layer; the side of the anti-reflective layer away from the UV-protective layer is uniformly coated with a protective outer layer; the coating is arranged from the inside out as an anti-blue light layer, an UV-protective layer, an anti-reflective layer, and a protective outer layer.

[0007] Furthermore, the anti-blue light layer is made of a transparent nanoscale metal oxide material; the metal oxide includes one or more of zinc oxide, titanium oxide, or cerium oxide.

[0008] Furthermore, the UV-protective layer uses an organic UV absorber or an inorganic UV shielding agent; the organic UV absorber includes benzotriazole compounds, and the inorganic UV shielding agent includes titanium dioxide or zinc oxide.

[0009] Furthermore, the anti-reflection layer is a multilayer interference film, which is composed of alternating layers of high-refractive-index materials and low-refractive-index materials; the high-refractive-index material includes titanium dioxide, and the low-refractive-index material includes silicon dioxide.

[0010] Furthermore, the protective outer layer is a fluoride coating; the fluoride includes perfluoropolyether or fluorinated alkylsilane.

[0011] Furthermore, the topcoat coating is uniformly applied to the surface of the eyeglass lens using vacuum coating, spin coating, or spray coating processes; the use of precision processes such as vacuum coating, spin coating, or spray coating ensures that the coating is uniform and of appropriate thickness.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention achieves the effect of protecting the eyes from blue light and ultraviolet radiation while improving the light transmittance, anti-fouling performance, and durability of the lens. Attached Figure Description

[0015] The markings in the attached diagram are: 1-Anti-blue light layer, 2-Anti-ultraviolet layer, 3-Anti-reflective layer, 4-Protective outer layer. Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings: Example

[0017] A type of anti-radiation protective coating for eyeglasses, such as Figure 1 As shown, the device includes a topcoat coating uniformly applied to the outer surface of the eyeglass lens; the topcoat coating includes an anti-blue light layer 1, an anti-ultraviolet layer 2, an anti-reflective layer 3, and a protective outer layer 4; the anti-blue light layer 1 is located on the innermost side and is uniformly coated on the outer surface of the eyeglass lens; the anti-ultraviolet layer 2 is uniformly coated on the side of the anti-blue light layer 1 away from ... anti-blue light layer 1; the anti-reflective layer 3 is uniformly coated on the side of the anti-ultraviolet layer 3 away from the anti-ultraviolet layer 2; the protective outer layer 4 is uniformly coated on the side of the anti-ultraviolet layer 3 away from the anti-ultraviolet layer 2; the topcoat coating is arranged from the inside out as the anti-blue light layer 1, the anti-ultraviolet layer 2, the anti-reflective layer 3, and the protective outer layer 4.

[0018] Working principle:

[0019] This utility model's topcoat coating includes an anti-blue light layer 1, an anti-ultraviolet layer 2, an anti-reflection layer 3, and a protective outer layer 4. The anti-blue light layer 1, located on the innermost side, is made of nanoscale metal oxide materials, including one or more of zinc oxide, titanium oxide, or cerium oxide. It can selectively absorb or reflect high-energy blue light with wavelengths in the range of 400nm to 500nm. By reducing the amount of blue light emitted from electronic device screens entering the eyes, it reduces the damage of blue light to the retina and relieves eye fatigue and dryness. The outer side of the anti-blue light layer 1 is uniformly coated with an anti-ultraviolet layer 2, which uses organic ultraviolet absorbers or inorganic ultraviolet shielding agents. Organic ultraviolet absorbers include benzotriazole compounds, and inorganic ultraviolet shielding agents include titanium dioxide or zinc oxide. It can effectively absorb or reflect wavelengths in the range of 400nm to 500nm. Ultraviolet rays in the range of 280nm to 400nm are protected; this layer prevents damage to the lens and retina, protecting eye health. An anti-reflective layer 3 is uniformly coated on the outer side of the anti-UV layer 2. The anti-reflective layer 3 is a multi-layer interference film composed of alternating layers of high-refractive-index and low-refractive-index materials. The high-refractive-index material includes titanium dioxide, and the low-refractive-index material includes silicon dioxide. Through the interference effect of light, it reduces reflected light from the lens surface, improves light transmittance, enhances visual clarity, and reduces glare interference to the eyes. A protective outer layer 4 is uniformly coated on the outer side of the anti-reflective layer 3. The protective outer layer 4 is a fluoride coating, including perfluoropolyether or fluorinated alkylsilane, which prevents dust, oil, and water stains from adhering to the lens surface, keeping the lens clean while improving its abrasion resistance and ease of cleaning.

[0020] Each functional layer is evenly distributed on the lens surface through a precision coating process, forming a composite coating. The layers work together to ensure high light transmittance and visual clarity of the lens, while also providing effective protection against blue light and ultraviolet rays, and improving the lens's anti-fouling and durability.

[0021] Although this disclosure has been described in detail with reference to exemplary embodiments, it is not limited thereto, and it will be apparent to those skilled in the art that various modifications and changes may be made thereto without departing from the scope of this disclosure.
