[0002] In recent years, sunglasses with totems have set off a trend in the industry. Existing totem lenses are made by vacuum plating the lenses, so that the surface of the lens substrate first forms a coating base layer, producing a multi-layer film color plating effect, and then using ink pad printing to attach the pattern to the lens to form an ink pad printing layer, and then vacuum plating, multi-layer spectrum superposition, to form a micro-line pattern coating layer with light and shadow refraction, and finally remove the ink. Such a totem effect has a complex structure and processing technology, high production cost, and low yield rate.

[0024] It should be noted that the terms up, down, left, right, inside, outside, first, second, etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the indicated technical features, unless otherwise clearly and specifically defined.
[0025] like Figures 1 to 3 As shown, the utility model discloses a totem multi-color lens 10, including a substrate 1, a color-changing layer 2, an anti-UV layer 3, a bridging layer (a first bridging layer 41 and a second bridging layer 42), a strengthening layer (a first strengthening layer 51 and a second strengthening layer 52), a totem layer 6 and an oil-proof layer (a first oil-proof layer 71 and a second oil-proof layer 72).
[0026] The lens substrate 1 is made of PC (polycarbonate) or PA (polyamide).
[0027] A color-changing layer 2 is formed on the outer surface of the substrate 1 by spin coating a color-changing liquid and curing molding process. The thickness of the color-changing layer 2 is controlled to be 3-5μm, and the optimal thickness is 4μm. The color-changing layer 2 allows the lens to become darker when the light is strong and lighter when the light is weak, thereby enhancing the lens's ability to restore depth and lightness, and at the same time, making the lens' color changeable.
[0028] An anti-UV layer 3 is provided on the outer surface of the color-changing layer 2 by coating an anti-UV coating, and the thickness of the anti-UV layer 3 is controlled to be 1.8-2.3 μm, and the optimal thickness is 2 μm. The anti-UV layer 3 enables the lens to have an anti-ultraviolet function, protects the eyes, avoids damage to the eyes by ultraviolet rays, and improves the use effect of the lens.
[0029] The first bridging layer 41 is provided on the outer surface of the UV-resistant layer 3 by coating a bridging agent, and the first strengthening layer 51 is provided on the outer surface of the first bridging layer 41 by coating a strengthening liquid. The thickness of the first bridging layer 41 is controlled to be 1.7-2.3 μm, with an optimal thickness of 2 μm, and the thickness of the first strengthening layer 51 is controlled to be 4.5-5.5 μm, with an optimal thickness of 5 μm. The combination of the first bridging layer 41 and the first strengthening layer 51 can not only strengthen the lens structure, but also facilitate the subsequent vacuum coating process.
[0030] The totem layer 6 is arranged on the outer surface of the first strengthening layer 51 by vacuum plating. The totem layer 6 is an anti-reflection film with a hollow pattern. The thickness of the totem layer 6 is controlled to be 2.8-3.5 μm, and the optimal thickness is 3 μm. The totem layer 6 makes the lens rich in design aesthetics. The manufacturing process of the totem layer 6 is relatively simple, the processing operation controllability is good, the cost is low, and the finished product quality is high. The light transmittance of the totem part is good, and the transmittance of the lens is guaranteed. The totem and the lens are perfectly and clearly combined, the pattern is clear, and the vision is not distorted. Moreover, the totem layer 6 is combined with the color-changing layer 2, and the totem effect is increased on the basis of the color change, and it has the ability to resist strong light irradiation. In the process of alternating strength of ambient light and changing depth of lens color, a more colorful effect can be transformed, and a looming hollow feeling is produced.
[0031] The first oil-proof layer 71 is provided on the outer surface of the totem layer 6 by coating. The thickness of the first oil-proof layer 71 is controlled to be 0.5-1.5 μm, and the optimal thickness is 1 μm. The first oil-proof layer 71 can protect the totem layer 6 and prevent fingerprints from contaminating the lens surface.
[0032] The second bridge layer 42 is formed on the inner surface of the substrate 1 by coating a bridge agent, and the second strengthening layer 52 is formed on the inner surface of the second bridge layer 42 by coating a strengthening liquid. The thickness of the second bridge layer 42 is controlled to be 1.7-2.3 μm, and the optimal thickness is 2 μm. The thickness of the second strengthening layer 52 is controlled to be 4.5-5.5 μm, and the optimal thickness is 5 μm. The combination of the second bridge layer 42 and the second strengthening layer 52 can not only strengthen the lens structure, but also facilitate the subsequent film layer processing.
[0033] The second oil-proof layer 72 is provided on the inner surface of the second strengthening layer 52 by coating. The thickness of the second oil-proof layer 72 is controlled to be 0.5-1.5 μm, and the optimal thickness is 1 μm. The second oil-proof layer 72 can prevent fingerprints and the like from contaminating the lens surface.
[0034] When the utility model is processed, the specific process steps are:
[0035] The first step is to make substrate 1:
[0036] The PC or PA material is dried, and then the PC or PA material is injection molded by an injection molding machine to form a lens substrate 1.
[0037] The second step is to make the color-changing layer 2:
[0038] By spin coating the color-changing liquid and then solidifying it, a color-changing layer 2 is formed on the outer surface of the substrate 1. The thickness of the color-changing layer 2 is controlled to be 3-5μm, so that the lens can become darker when the light is strong and lighter when the light is weak.
[0039] The third step is to make the anti-UV layer 3:
[0040] By coating the anti-UV coating, an anti-UV layer 3 is formed on the outer surface of the color-changing layer 2, and the thickness of the anti-UV layer 3 is controlled to be 1.8-2.3 μm, so that the lens has an anti-UV function, protects the eyes, and avoids damage to the eyes by ultraviolet rays.
[0041] Step 4: Make the bridging layer and strengthening layer:
[0042] By coating a bridging agent, a first bridging layer 41 and a second bridging layer 42 are formed on the outer surface of the UV-resistant layer 3 and the inner surface of the substrate 1, respectively, and the thickness of the first bridging layer 41 and the second bridging layer 42 is controlled to be 1.7-2.3 μm.
[0043] Then, by coating the strengthening liquid, the first strengthening layer 51 and the second strengthening layer 52 are formed on the outer surface of the first bridge layer 41 and the inner surface of the second bridge layer 42 respectively, and the thickness of the first strengthening layer 51 and the second strengthening layer 52 is controlled to be 4.5-5.5 μm.
[0044] The combination of the first bridge layer 41 and the first strengthening layer 51 , and the combination of the second bridge layer 42 and the second strengthening layer 52 can strengthen the lens structure, which is beneficial to subsequent film layer processing.
[0045] Step 5: Make totem layer 6:
[0046] Through vacuum plating technology, an anti-reflection film with a hollow pattern is formed on the outer surface of the first strengthening layer 51. The anti-reflection film with a hollow pattern is the totem layer 6. The thickness of the totem layer 6 is controlled to be 2.8-3.5μm. The totem layer 6 makes the lens rich in design aesthetics, with clear patterns and no visual distortion. Moreover, the totem layer 6 is combined with the color-changing layer 2 to create a more colorful effect.
[0047] Step 6: Make an oil-proof layer:
[0048] By coating, a first oil-proof layer 71 and a second oil-proof layer 72 are respectively formed on the outer surface of the totem layer 6 and the inner surface of the second strengthening layer 52, and the thickness of the first oil-proof layer 71 and the second oil-proof layer 72 is controlled to be 0.5-1.5 μm, so as to protect the totem layer 6 and prevent fingerprints and the like from contaminating the lens surface.
[0049] At this point, the production of the totem multi-color lens 10 of the utility model is completed.
[0050] In addition, the totem multi-color lens 10 of the utility model can also be made into a non-polarized lens or a polarized lens as needed, so that the product has a polarization function. Specifically, as shown in the figure, a polarizing film 8 can be arranged on the outer surface of the substrate 1, and a color-changing layer 2, an anti-UV layer 3, a first bridging layer 41, a first strengthening layer 51, a totem layer 6 and a first oil-proof layer 71 can be arranged on the outer surface of the polarizing film 8 in sequence. Alternatively, a polarizing film is arranged on the inner surface of the substrate 1, and a second bridging layer 42, a second strengthening layer 52 and a second oil-proof layer 72 can be arranged on the inner surface of the polarizing film in sequence.
[0051] Product test results of the utility model: the lens almost completely filters ultraviolet rays (light waves below 400nm). When the lens is in light color, the transmittance of other bands (light waves above 400nm) is 70-80%. When the lens becomes dark, the transmittance of other bands (light waves above 400nm) decreases. The overall transmittance of the product is high. While having the beauty of totem design, the vision of the lens is still clear and transparent, allowing the wearer to see very clearly in any environment. It complies with international standards ISO12312-1:2022, Australian standards AS / NZS1067.1:2016 and American standards ANSI Z80.3-2018.
[0052] The above is only an example of the implementation of the utility model, and is not intended to limit the protection scope of the utility model. It should be pointed out that equivalent changes made by technicians in this field according to the design ideas of this case after reading this specification all fall within the protection scope of this case.
