Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of lenses, in particular to a matte coated lens, a manufacturing method thereof and eyeglasses. BACKGROUND

[0002] Commonly seen on the market, protective glasses, goggles, ski goggles and sunglasses, etc., the basic principle is to add different colors in transparent lens material to form colored lenses. This coloring process can effectively filter out harmful ultraviolet rays and too intense visible light (glare), significantly reducing the pressure and fatigue of the wearer's eyes, providing a more comfortable, safe field of view.

[0003] A further design is a coated lens. The outer layer of such a lens is covered with a special metal reflective film, giving the lens a unique luster, and reflecting most of the incident light like a mirror. Therefore, when viewed from the outside, the lens will strongly reflect light, reflecting the surrounding environment, thus cleverly hiding the wearer's eyes, making it difficult for the outside world to pry. This mirror design not only has a strong fashion sense, but also provides privacy while effectively blocking strong light, enhancing the wearing experience.

[0004] The manufacturing process of the existing coated lens is as follows: as shown in Figure 1 (a), first, a lens body layer 1 with a frosted surface is injection molded in a frosted mold, the surface of the lens body layer 1 has a concave-convex frosted surface 1a; second, a coating layer 2 is formed on the frosted surface 1a of the lens body layer 1, the coating layer 2 is a thin layer with almost uniform thickness, so the outer surface of the coating layer 2 forms a concave-convex surface 2a, and the coating layer 2 with the concave-convex surface 2a performs diffuse reflection on light, thus having a metallic misty luster in appearance; third, a glue layer 3 is coated on the concave-convex surface 2a of the coating layer 2, the glue layer 3 can fill the concave-convex surface 2a, so that the lens becomes transparent in field of view, to obtain a lens that has both metallic misty luster in appearance and transparent field of view; finally, a second lens layer 4 is bonded to the concave-convex surface 2a of the coating layer 2 through the glue layer 3, the second lens layer 4 can play a role of strengthening and protection; of course, in another existing embodiment, as shown in Figure 1 (b), the glue layer 3 can also not be provided, and a strengthening treatment layer 4' is formed on the concave-convex surface 2a of the coating layer 2, and the concave-convex surface 2a is filled by the strengthening treatment layer 4'. The strengthening treatment layer 4' can be formed by existing technical means, such as by immersing the lens in a hardening liquid pool to make the surface adhere to the strengthening treatment layer 4'. The coated lens formed by the above process can not only reflect the light from the outside, but also have a matte visual effect. However, the existing technical process is relatively complex, the production efficiency is not high enough, and the cost of the frosted mold is high, resulting in high overall cost. SUMMARY

These drawings are part of the disclosure of the present invention, primarily used to illustrate the embodiments and to explain the operating principles of the embodiments in conjunction with the relevant descriptions in the specification. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0047] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0048] Example 1

[0049] like Figure 2 As shown, this embodiment provides a matte coated lens 100, including a lens substrate 10, an AG film 20, a coating layer 30, and a filler protective layer 40. The lens substrate 10 is an optical lens made of a light-transmitting material, such as polycarbonate (PC) or nylon (PA). In other embodiments, the lens substrate 10 may also be made of synthetic resins such as PMMA (polymethyl methacrylate), CR-39 (allyl diethylene glycol), PC (polycarbonate), PA (nylon), TAC (triacetate film), or PS (styrene), or glass. In this embodiment, the lens substrate 10 uses PC plastic or PA resin lenses, both of which are widely used as alternatives to glass eyeglass lenses due to their excellent light transmittance and impact resistance.

[0050] AG (Anti-Glare) film, also known as anti-glare film, matte protective film, or frosted protective film, uses a rough surface texture to scatter light, reducing specular reflection and thus glare. It's commonly used for surface protection of computer screens. It reduces bright spots caused by reflections, ensuring good screen visibility at different angles and minimizing interference from ambient light, making the screen content easier to see. The working principle of AG film is that its surface has tiny uneven structures that scatter light. These structures cause incident light to reflect in different directions, reducing the amount of light directly reflected to the viewer's eyes. This scattering effect allows the screen to maintain good readability even under direct sunlight. AG membranes are currently known membrane materials. They can be PET, TAC, PMMA, PC, and PA membranes with AG functions, manufactured using methods such as microparticle addition or phase separation technology. Companies such as DNP, Electrical Engineering, 3M, ClearCal, Lexerd, Celicious, iLLumiShield, Skinomi, i-Tronixs, GENERIC, Book Pub, Yongju Technology, and Excelite all have mature products that are widely used and readily available. Their manufacturing processes are mature and will not be elaborated here.

[0051] The AG film 20 is a film material, including a first surface 21 and a second surface 22 opposite to the first surface 21. The first surface 21 is an uneven surface, and the second surface 22 is a flat surface. Of course, in some other embodiments, the second surface 22 of the AG film 20 may also be an uneven surface.

[0052] In this embodiment, the lens substrate 10 is bonded to the second surface 22 of the AG film 20. The lens substrate 10 is manufactured by in-mold injection molding of a high-temperature molten light-transmitting polymer material (such as PC, PA, PMMA, etc.) into a mold cavity where the AG film 20 is positioned. This allows an AG film 20 to be directly and firmly attached to the optical polymer material lens substrate 10. The polymer material of the lens substrate 10 is preferably selected to be heat-resistant and impact-resistant, reducing the safety hazard of eye injury due to impact damage to the lens substrate 10, such as the aforementioned PC and PA materials. Furthermore, to ensure the reliability of the bonding between the lens substrate 10 and the AG film 20 and to ensure the final optical performance of the lens, it is preferable to use lens substrates 10 and AG films 20 of the same material for in-mold injection molding, such as both being made of PC material.

[0053] This embodiment combines the lens substrate 10 with the AG film 20, so that the outer surface of the lens body also has a frosted surface. Compared with the manufacturing method of injection molding the body layer 1 with the frosted surface 11 in the existing technology, this embodiment not only reduces the manufacturing cost, but also, because the AG film 20 can be manufactured by microparticle addition, phase separation technology, chemical etching, or physical sandblasting, the performance of the uneven surface (frosted surface) of the AG film 20 is better than that of the frosted surface formed by injection molding in the frosted mold. This also provides a more favorable foundation for the subsequent coating layer 30 operation, so that the final matte coated lens 100 not only has a lower manufacturing cost, but also excellent optical performance and frosted appearance.

[0054] The coating layer 30 is bonded to the first surface 21 of the AG film 20. The coating layer 30 is defined as located on the outer side of the AG film 20, with the area of ​​the coating layer 30 facing away from the AG film 20 being defined as the exterior. The coating layer 30 serves to reflect light incident on the matte coated lens 100 from the outside. The coating layer 30 is manufactured through a coating process. For example, a vacuum evaporation method can be used. Vacuum evaporation involves placing any one of the following materials into a metal container: a low-refractive-index material (such as silicon dioxide SiO2 or magnesium fluoride MgF2), a high-refractive-index material (such as titanium dioxide TiO2, zirconium oxide ZrO2, or tantalum oxide Ta2O5), or a metallic material (such as aluminum or indium). A vacuum environment is created inside the container, and the coating material is vaporized and deposited onto the surface of the target (lens) by resistance or electron beam heating. Since this vacuum evaporation method can employ known methods such as sputtering, electron beam evaporation, or ion beam evaporation, it will not be described in detail here.

[0055] The coating layer 30 is a thin layer with an almost uniform thickness. Therefore, the outer surface 31 of the coating layer 30 is formed as an uneven surface to give the lens a metallic hazy luster. Furthermore, such coated lenses are prone to scratches due to their low surface hardness, especially for lenses made of materials such as PC plastic or PA resin. To address this scratch-prone nature, a protective layer can be formed on the lens surface. In this embodiment, a leveling protective layer 40 is also bonded to the coating layer 30. The leveling protective layer 40 has a flat outer surface, which can fill in the uneven outer surface 31 of the coating layer, thus giving the lens a clear field of vision. The leveling protective layer 40 can be a strengthening treatment layer 41 formed by immersing at least part of the lens in a container containing a strengthening coating solution. Therefore, the coating layer 30 is protected by the leveling protective layer 40, and the surface hardness is also improved, thereby increasing its abrasion resistance. In some other embodiments, the reinforcing layer 41 is bonded to the surface of the lens assembly consisting of the lens substrate 10, the AG film 20, and the coating layer 30, forming an overall outer covering effect. In this way, the lens substrate 10, the AG film 20, and the coating layer 30 are all protected by the reinforcing layer 41, resulting in better protection.

[0056] The matte coated lens 100 provided in this embodiment is manufactured using widely used AG film material. This eliminates the need for expensive atomizing molds, significantly reducing manufacturing costs and simplifying the processing to some extent, further improving production efficiency. The matte coated lens 100 made with AG film, with its textured surface and frosted effect, reflects external light, cleverly concealing the wearer's eyes and protecting their privacy. Furthermore, the matte finish of the AG film's textured surface prevents direct light reflection, resulting in a softer, glare-free appearance. When used in ordinary eyeglasses, sunglasses, or goggles, this provides a gentler, more pleasant impression. Simultaneously, it maintains a clear field of vision for the wearer, greatly enhancing the wearing experience.

[0057] Example 2

[0058] Reference Figure 3This embodiment provides a matte coated lens 100a, which differs from Embodiment 1 in that the leveling protective layer 40a in this embodiment is not a strengthening layer formed by immersing the lens in a container containing a strengthening coating solution. The rest of this embodiment is the same as Embodiment 1. In this embodiment, the leveling protective layer 40a includes a first adhesive layer 42 and a protective lens layer 43. The protective lens layer 43 is bonded to the uneven outer surface 31 of the coating layer 30 via the first adhesive layer 42. The protective lens layer 43 serves to reinforce and protect the surface, while the first adhesive layer 42 fills in the uneven outer surface 31 of the coating layer 30. This process has low requirements for equipment and raw materials and is simpler to operate.

[0059] Example 3

[0060] Reference Figure 4 This embodiment provides a matte coated lens 100b, which differs from Embodiment 1 in that the lens substrate 10 in this embodiment is not bonded to the AG film 20 using in-film injection molding. Instead, the lens substrate 10 is bonded to the second surface 22 of the AG film 20 by setting a second adhesive layer 50. The rest of this embodiment is the same as Embodiment 1. This embodiment simplifies the processing flow of the matte coated lens, but since the lens substrate 10 and the AG film 20 are bonded by adhesive, the performance stability of the lens will be slightly inferior to that of Embodiment 1. Preferably, the bonded lens substrate 10 can be PMMA (polymethyl methacrylate), PC (polycarbonate), PA (nylon), or TAC (triacetate film), consisting of one or more layers bonded together, and formed into the required curved surface of the lens by bending or pressing.

[0061] Example 4

[0062] Reference Figure 5 This embodiment provides a matte coated lens 100c, which differs from Embodiment 3 in that the leveling protective layer 40a in this embodiment is not a strengthening layer formed by immersing the lens in a container containing a strengthening coating solution. The rest of this embodiment is the same as Embodiment 3. In this embodiment, the leveling protective layer 40a includes a first adhesive layer 42 and a protective lens layer 43. The protective lens layer 43 is bonded to the uneven outer surface 31 of the coating layer 30 via the first adhesive layer 42. The protective lens layer 43 serves to reinforce and protect the surface, while the first adhesive layer 42 fills in the uneven outer surface 31 of the coating layer 30. This process has low requirements for equipment and raw materials and is simpler to operate.

[0063] Example 5

[0064] Reference Figure 6This embodiment provides a matte coated lens 100d, which differs from Embodiment 1 in that a functional layer 60 is bonded between the lens substrate 10 and the AG film 20. The rest is the same as in Embodiment 1. The functional layer 60 may include one or more of a polarizing layer, a photochromic layer, an ultraviolet filter layer, and a blue light filter layer to provide more functions and further enhance the protective effect. For example, the polarizing layer can enable the lens to have a polarizing function, filtering out stray light, reducing glare caused by reflections from water, snow, or sunlight, and reducing strong light stimulation, improving visual clarity, and relieving eye strain. The functional layer 60 can be bonded to the AG film 20 by the in-film injection molding method described above, or by an adhesive layer. Similarly, the lens substrate 10 can be bonded to the functional layer 60 by the in-film injection molding method described above, or by an adhesive layer.

[0065] In this embodiment, the functional layer 60 is described as being bonded between the lens substrate 10 and the AG film 20. However, it is not limited to this. In other embodiments, the functional layer 60 may be bonded to the inner side of the lens substrate 10, which is also a feasible technical solution.

[0066] Furthermore, in this embodiment, the leveling protective layer 40 can be a reinforcing layer 41 formed by immersing at least a portion of the lens in a container containing a reinforcing coating solution. Alternatively, the leveling protective layer can also include an adhesive layer and a protective lens layer. In this embodiment, the protective lens layer is bonded to the uneven outer surface of the coating layer via the adhesive layer, providing both reinforcement and protection, while the adhesive layer levels the uneven outer surface of the coating layer.

[0067] Example 6

[0068] Reference Figure 7 This embodiment is a further simplification based on the above embodiment 5. In this embodiment, the matte coated lens 100e is an AG film 20 directly combined with a functional layer 60 that has a single-layer function or a multi-layer composite function. Since the film (such as a polarizing film or a polarizing photochromic film) that serves as the functional layer 60 is composed of multi-layer film materials, it has a certain strength and elasticity. In some applications that require thinness, the functional layer 60 can also be directly used as the lens substrate 10 to achieve the basic strength support function; in other words, the lens substrate 10 is the functional layer 60.

[0069] Example 7

[0070] Reference Figure 8This embodiment provides a method for manufacturing a matte coated lens 100, wherein the matte coated lens 100 is the matte coated lens 100 provided in Embodiment 1, and includes the following steps:

[0071] S1: Provide an AG film 20 and a molding die with a cavity; the AG film 20 is a film material, including a first surface 21 and a second surface 22 opposite to the first surface 21, wherein the first surface 21 is an uneven surface;

[0072] S2: Position the AG film 20 in the mold cavity, wherein the first surface 21 of the AG film 20 is positioned away from the mold cavity;

[0073] S3: A lens substrate 10 is manufactured by in-film injection molding of a high-temperature molten material into a mold cavity where the AG film 20 is positioned; specifically, the lens substrate 10 is attached to the flat second surface 22 of the AG film 20.

[0074] S4: A coating layer 30 is formed on the uneven first surface 21 of the AG film 20 by a coating process; the coating process is, for example, vacuum evaporation.

[0075] S5: A strengthening layer 41 is formed by immersing at least a portion of the lens generated in step S4 into a container containing a strengthening coating solution and subjecting it to a strengthening process. The strengthening layer 41 serves as a leveling protective layer 40 and is formed at least on the coating layer 30. The strengthening process may include baking, etc.

[0076] More specifically, in step S2, positioning the AG film 20 in the mold cavity further includes pre-bending the AG film 20 to fit into the mold cavity in order to provide the curvature required for the formed lens.

[0077] In some other embodiments, the reinforcing layer 41 is formed on the surface of the lens assembly consisting of the lens substrate 10, the AG film 20, and the coating layer 30, forming a covering effect. In this way, the lens substrate 10, the AG film 20, and the coating layer 30 are all protected by the reinforcing layer 41, resulting in better protection.

[0078] Example 8

[0079] Reference Figure 9 This embodiment provides a matte coated lens 100f, which differs from embodiment 5 in that the lens substrate 10f in this embodiment is different from that in embodiment 5. This embodiment further defines the functional layer 60 that bonds the lens substrate 10f and the AG film 20 in the matte coated lens 100f, while the rest is the same as in embodiment 5.

[0080] In this embodiment, the functional layer 60 is specifically a color powder sheet 61. The color powder sheet 61 can be made by adding a set proportion of color powder to a color powder sheet matrix material (such as a resin material), so that the final lens is formed as a colored lens. The color of the color powder can be selected according to actual needs to make colored lenses of different colors. The color powder sheet matrix material can be a synthetic resin material such as PMMA (polymethyl methacrylate), CR-39 (allyl diethylene glycol), PC (polycarbonate), PA (nylon), or PS (styrene).

[0081] The main function of tinted lenses is to filter light, reduce glare and strong light, and improve visual contrast. Different colored lenses have different light-filtering effects, thus their functions and applicable scenarios vary. For example, gray lenses are the most common lens color because they can evenly filter various colors of light, maintaining the original colors of objects while effectively reducing light intensity. Gray lenses are suitable for most weather conditions, especially for daily use and driving; brown (or tan) lenses: Brown lenses can filter out a large amount of blue light, thereby improving visual contrast and clarity. They perform well in foggy or heavily polluted weather and can also enhance the sense of distance in objects; and there are also yellow, green, red (pink) lenses, etc., which will not be listed in detail here.

[0082] In this embodiment, lens 100f is made using a pigment sheet 61. Because the thickness of the pigment sheet 61 is essentially uniform, the resulting lens has a uniform color. Especially when manufacturing lenses with varying thicknesses, there is no color difference where thicker areas are darker than thinner areas, thus avoiding a negative impact on the wearing experience. For example, in this embodiment, the lens substrate 10f is a concave lens, which can ultimately be used to manufacture corrective eyeglasses. Furthermore, the pigment sheet 61 is located on the inner side and protected by other structures. In particular, in this embodiment, the pigment sheet 61 is positioned between the lens substrate 10f and the AG film 20, preventing scratches that could damage it and ensuring its light-filtering effect. Compared to the dip-coating method of depositing a pigment-based light-blocking film onto the lens, this method is more robust and reliable.

[0083] The toner sheet 61 can be bonded to the AG film 20 by the in-film injection molding method described above, or it can be bonded to the AG film 20 by an adhesive layer. Similarly, the lens substrate 10 can be bonded to the toner sheet 61 by the in-film injection molding method described above, or the lens substrate 10 can be bonded to the toner sheet 61 by an adhesive layer.

[0084] Example 9

[0085] Reference Figure 10This embodiment provides a matte coated lens 100g, which differs from Embodiment 6 in that the lens substrate 10g in this embodiment is different from that in Embodiment 6. This embodiment further defines the functional layer 60 between the lens substrate 10g and the AG film 20 in the matte coated lens 100g, while the rest is the same as in Embodiment 6.

[0086] In this embodiment, the functional layer 60 specifically includes a color powder sheet 61 and a polarizing film 62, with the color powder sheet 61 located inside the polarizing film 62. The color powder sheet 61 can be made by adding a corresponding proportion of color powder to a color powder substrate material (such as a resin material), so that the final lens is formed as a colored lens. The color of the color powder can be selected according to actual needs to make colored lenses of different colors. The color powder substrate material can be a synthetic resin material such as PMMA (polymethyl methacrylate), CR-39 (allyl diethylene glycol), PC (polycarbonate), PA (nylon), or PS (styrene).

[0087] Adding a polarizing film to the pigment film is mainly to ensure that the sunglasses lens still performs well in certain special situations, such as outdoor fishing. In this case, the main function of the sunglasses lens is to filter ultraviolet rays, so the color of the sunglasses lens is usually dark, that is, the pigment film contains dark pigments. However, dark sunglasses lenses can make it difficult to see the float on the water surface. If the color of the sunglasses lens is light, the light reflected from the water surface may cause glare. Therefore, when a polarizing film is added to the pigment film, the color of the pigment film can be light, and the polarizing film can block the stronger horizontal light component in these dazzling glare.

[0088] The toner sheet 61 can be bonded to the polarizing film 62 by the in-film injection molding method described above, or it can be bonded to the polarizing film 62 by an adhesive layer. Similarly, the lens substrate 10 can be bonded to the toner sheet 61 by the in-film injection molding method described above, or the lens substrate 10 can be bonded to the toner sheet 61 by an adhesive layer.

[0089] In this embodiment, the lens 100g is made of pigment sheet 61. Since the thickness of pigment sheet 61 is basically uniform, the resulting lens has a uniform color. Especially when making lenses with varying thicknesses, there will be no color difference phenomenon that would affect the wearing experience due to thicker areas being darker than thinner areas. For example, in this embodiment, the lens substrate 10g is a convex lens, which can ultimately be used to manufacture vision correction glasses.

[0090] In this embodiment, the polarizing film 62 can also be replaced with a color-changing film, etc.
