Description

Technical Field

[0001] This utility model relates to the technical field of lenses, specifically to a color-changing lens with a dazzling coating. Background Technology

[0002] Currently, there are many types of iridescent coated lenses on the market, with a wide variety of colors. These lenses primarily utilize vacuum sputtering coating technology to deposit an iridescent film layer onto a photochromic or polarizing substrate. The substrate enhances light reflection through photochromic or polarizing methods, making the iridescent film's colors more vibrant. The more abundant the light and the deeper the substrate color, the more vibrant the colors reflected by the iridescent film.

[0003] However, traditional color-changing substrates are formed by spraying or immersing in color-changing liquid to create the color-changing layer. The color-changing effect is limited, usually only turning gray or brown. Furthermore, direct coating on the color-changing layer is prone to cracking. Color-changing substrates that are sprayed or immersed in color-changing liquid often fail the RSL report (Restricted Substances List Report) test.

[0004] In view of this, the inventor, relying on his long-accumulated professional knowledge and familiarity with lens products, conducted in-depth research and a large number of experiments and tests, and specially developed and designed a new type of iridescent color-changing lens that is of guaranteed quality, has diverse and fast color-changing properties, can pass RSL, and effectively protects the health and safety of consumers. This invention thus came into being. Utility Model Content

[0005] The purpose of this invention is to provide a colorful film-changing lens that makes the film layer firm and crack-free, with diverse and fast color changes, bright and vivid colors, and full colors. It can pass RSL testing to ensure product quality.

[0006] To achieve the above objectives, the solution of this utility model is: A photochromic lens comprises a substrate, a photochromic polarizing layer, a bridging layer, a reinforcing layer, a photochromic coating layer, and a waterproof layer. The photochromic polarizing layer is disposed on the convex surface of the substrate. This layer is composed of a photochromic coating layer, an adhesive layer, and a PVA layer. The PVA layer is bonded to the photochromic coating layer on both the front and back sides via adhesive layers, forming a composite structure. On the convex surface of the photochromic polarizing layer, the bridging layer, reinforcing layer, photochromic coating layer, and waterproof layer are sequentially disposed from the lens center outwards. On the concave surface of the substrate, the bridging layer, reinforcing layer, and waterproof layer are sequentially disposed from the lens center inwards.

[0007] The substrate is made of PC (polycarbonate) or PA (polyamide).

[0008] The thickness of the substrate is 1.95-2.03 mm.

[0009] The thickness of the color-changing polarizing layer is 12-18µm.

[0010] The thickness of the color-changing film layer is 3-5µm, and the thickness of the PVA layer is 4-6µm.

[0011] The thickness of the bridging layer is 1.8-2.1µm.

[0012] The thickness of the reinforcing layer is 0.5-0.55µm.

[0013] The coating density of the reinforced layer is 0.98-1.0 g / ml, the viscosity is 15-25 cp, the solid content is 31-33 wt%, and the pH value is 8.5.

[0014] The iridescent film is formed by alternating coatings of SiO2 and ZrO2.

[0015] The thickness of the iridescent film layer is 2.5-3.2µm.

[0016] The thickness of the waterproof layer is 0.4-1.4µm.

[0017] With the above structure, the photochromic polarizing layer of this invention not only reduces glare through the PVA layer and the photochromic film layer, but also achieves diverse color-changing effects through the double-layer photochromic film layer. Different photochromic film layers can be selected to display various colors such as blue, red, brown, and green, and the color-changing speed is fast. Furthermore, this invention uses a bridging layer and a reinforcing layer to firmly bond the iridescent film layer to the convex surface of the photochromic polarizing layer, effectively preventing film cracking and resulting in vibrant colors on the lens surface. Especially under outdoor sunlight, the colors are bright, vivid, and saturated, and the lens surface feels silky smooth when worn, making the product suitable for various outdoor activities. Simultaneously, this invention can pass RSL testing to ensure product quality, effectively protect consumer health and safety, and promote the sustainable development of domestically produced lenses in the global trade.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model. It should be noted that the terms "upper," "lower," "left," "right," "inner," "outer," "first," and "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the indicated technical features, unless otherwise explicitly defined. like Figures 1 to 4 As shown, this utility model discloses a color-changing film lens, which is composed of a substrate 1, a color-changing polarizing layer 2, a bridging layer 3, a reinforcing layer 4, a color-changing film layer 5, and a waterproof layer 6.

[0022] The substrate 1 is made of PC (polycarbonate) or PA (polyamide). The thickness of the substrate 1 is controlled to be 1.95-2.03 mm.

[0023] A photochromic polarizing layer 2 is disposed on the convex surface of substrate 1. The photochromic polarizing layer 2 is composed of a photochromic film layer 21, an adhesive layer 22, and a PVA layer 23. The photochromic film layer 21 is bonded to the front and back sides of the PVA layer 23 via the adhesive layer 22, forming a sandwich-like composite structure. The thickness of the photochromic polarizing layer 2 is controlled to be 12-18 µm, wherein the thickness of the photochromic film layer 21 is controlled to be 3-5 µm, and the thickness of the PVA layer 23 is controlled to be 4-6 µm. The photochromic polarizing layer 2 is heat-treated and tightly bonded to the ejected substrate 1. In this way, the sandwich-type composite structure of the color-changing polarizing layer 2 can not only reduce glare by using the PVA layer 23 and the color-changing film layer 21, but also achieve a variety of color-changing effects by using the double-layer color-changing film layer 21. By selecting different combinations of color-changing film layers 21, it can present a variety of colors such as blue, red, brown, and green. Moreover, the double-layer color-changing film layer 21 changes color quickly.

[0024] On the convex surface of the photochromic polarizing layer 2, a bridging layer 3, a reinforcing layer 4, a color-enhancing film layer 5, and a waterproof layer 6 are sequentially arranged from the center of the lens outwards. On the concave surface of the substrate 1, the bridging layer 3, the reinforcing layer 4, and the waterproof layer 6 are sequentially arranged from the center of the lens inwards. Bridging layers 3 are formed on the convex surface of the photochromic polarizing layer 2 and the concave surface of the substrate 1 by coating with a bridging agent, and the thickness of the bridging layer 3 is controlled to be 1.8-2.1µm. The surfaces of the two bridging layers 3 are coated with a reinforcing liquid coating to form a reinforcing layer 4, the thickness of which is controlled to be 0.5-0.55µm, and the coating density of the reinforcing layer 4 is 0.98-1.0g / ml, the viscosity is 15-25cp, the solid content is 31-33wt%, and the pH value is 8.5. The surface of the convex reinforcing layer 4 is coated with a iridescent film layer 5, which is formed by alternating SiO2 and ZrO2 coatings, with a thickness controlled at 2.5-3.2µm. The surfaces of the concave reinforcing layer 4 and the iridescent film layer 5 are coated to form a waterproof layer 6, with a thickness controlled at 0.4-1.4µm. Thus, the photochromic film layer 21, together with the bridging layer 3 and the reinforcing layer 4, can firmly bond with the iridescent film layer 5, effectively preventing film cracking and resulting in vibrant colors on the lens surface.

[0025] This novel photochromic lens, through effective absorption of ultraviolet rays from ambient light sources, rapidly changes color to blue, red, brown, and green, offering a rich variety of hues. Conversely, it fades quickly upon removal of ultraviolet light, providing greater comfort for the wearer. In summary, this lens's rapid color change effectively prevents sunlight stimulation, helping the eyes adapt better to environmental changes. It displays a rich array of colors under sunlight, meeting the needs of various occasions. The double-layer photochromic film process simplifies the manufacturing process, saves time, and significantly improves the yield rate. The product passes RSL testing, ensuring product quality, safety, and health. This novel lens can be electroplated with various colors of photochromic film, providing greater wearing comfort and a wide range of colors to meet consumers' dream choices for UV protection.

[0026] like Figure 4 As shown, the product testing results of this utility model are as follows: the lens almost completely filters light waves (ultraviolet rays) below 400nm. When the lens is light-colored, the light transmittance of light waves from 400nm to 680nm is 45-85%. When the lens becomes dark-colored, the light transmittance of light waves from 400nm to 680nm decreases to 5-55%. The product complies with international standard ISO 12312-1:2022, Australian standard AS / NZS 1067.1:2016 and American standard ANSI Z80.3-2018, and can pass RSL testing.

[0027] The above description is merely an example of the implementation of this utility model and is not intended to limit the scope of protection of this utility model. It should be noted that any equivalent changes made by those skilled in the art after reading this specification, based on the design concept of this case, shall fall within the scope of protection of this case.
