Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of lenses, in particular to a nylon polarized lift-up display lens. Background Art
[0002] Polarized lenses, as they are commonly used, filter out light from specific directions, providing a clearer field of view and reducing eye strain. Typically, polarized lenses have a polarization efficiency of 98%-99%, or even higher. However, this effect can cause problems when viewing screens. Because light emitted by screens has multiple polarization directions, existing high-efficiency polarized lenses only allow light from a specific direction to pass through. This can cause the screen to appear dim or blurry after filtering out most of the light. LCD screens, in particular, are a prime example of using polarized light. They use two polarizers placed tightly against the liquid crystal glass to generate a variety of light types, including natural light, plane polarized light, partially polarized light, elliptically polarized light, and circularly polarized light. These polarization types are selected and applied to provide excellent picture quality and visual experience, forming the foundation for LCD screens to display images. However, if any of the polarizers is missing, the LCD display will not display images properly. Existing high-efficiency polarized lenses, on the other hand, filter out most of the polarized light, causing the LCD screen to appear dim and the displayed content to become unreadable. Specifically, for cars equipped with a head-up display function, it is even more difficult to see the head-up display content when wearing existing polarized glasses.
[0003] In view of this, the inventor, relying on many years of experience in the development, design and production of eyewear products, has specially developed a new type of nylon polarized lift-up display lens, which gave rise to this case. Utility Model Content
[0004] The purpose of the utility model is to provide a nylon polarized lift-up display lens to reduce the polarization efficiency of the lens, making it easier to see the content displayed on the screen, and the lens meets the requirements of the aging test.
[0005] In order to achieve the above objectives, the solution of the present invention is:
[0006] A nylon polarized lift-up display lens comprises a PA nylon lens with a polarizing film laminated thereon to form a lens base layer, wherein the polarizing film has a polarization efficiency of 80%-85%. A composite strengthening layer is provided on both the inner and outer sides of the lens base layer, the composite strengthening layer comprising a first strengthening layer and a second strengthening layer, wherein the first strengthening layer is an X4 strengthening liquid coating layer, and the second strengthening layer is an X7 strengthening liquid coating layer. An anti-reflection film layer is provided on the inner composite strengthening layer; a waterproof layer is provided on the anti-reflection film layer; a waterproof layer is provided on the outer composite strengthening layer; and an oil-proof layer is provided on both the inner and outer waterproof layers.
[0007] The thickness of the PA nylon lens is 1.8-3.0 mm.
[0008] The thickness of the composite strengthening layer is 4-9 μm.
[0009] The thickness of the anti-reflection film layer is 90-110 nm.
[0010] The thickness of the waterproof layer is 8-15nm.
[0011] The thickness of the oil-proof layer is 8-15 nm.
[0012] By adopting the above solution, the present invention achieves the following beneficial effects: combining PA nylon lenses with a polarizing film with a polarization efficiency of 80%-85%. The low polarization efficiency of the polarizing film allows the lens base layer to still filter out some light from specific directions, providing a relatively clearer field of vision and reducing eye fatigue. Furthermore, by reducing the polarization efficiency of the polarizing film, the percentage of screen light filtered out when viewing an LCD screen through the final lens product of the present invention is reduced. As a result, the screen will only dim slightly, but the content displayed on the screen can still be easily seen. For cars equipped with head-up displays, wearing the glasses of the present invention provides a clearer view of the head-up display. Furthermore, by applying a two-layer composite strengthening layer, the present invention achieves a solid bond between the low polarization efficiency polarizing film and the vacuum-evaporated anti-reflection film layer, ensuring the wear and scratch resistance of the lens. The anti-reflection film layer not only reduces the reflection of light from the back of the lens to the eye, but also improves vision. Furthermore, the composite strengthening layer ensures that the lens product passes aging tests and meets the requirements of GB39552.1-2020 for sunglasses and sun lenses. In addition, the utility model plays the role of waterproofing and preventing oil pollution through the waterproof layer and the oil-proof layer.

[0023] See also Figure 1-2 As shown, the present invention discloses a nylon polarized lift-up lens, wherein a polarizing film 2 is laminated on a PA nylon lens 1 to form a lens base layer 10. The thickness of the PA nylon lens 1 is 1.8-3.0 mm, and the polarization efficiency of the polarizing film 2 is 80%-85%.
[0024] A composite strengthening layer 3 is applied to both the inner and outer sides of the lens base layer 10. The composite strengthening layer 3 comprises a first strengthening layer 31 and a second strengthening layer 32. The first strengthening layer 31 is coated with an X4 strengthening solution, while the second strengthening layer 32 is coated with an X7 strengthening solution. The X4 and X7 strengthening solutions can be manufactured by SDC (USA). The thickness of the composite strengthening layer 3 is 4-9 μm.
[0025] An anti-reflection film layer 4 is provided on the inner composite strengthening layer 3. The thickness of the anti-reflection film layer 4 is 90-110 nm.
[0026] A waterproof layer 5 is provided on the anti-reflection film layer 4, and a waterproof layer 5 is provided on the outer composite strengthening layer 3. The thickness of the waterproof layer 5 is 8-15 nm.
[0027] An oil-proof layer 6 is provided on each of the inner and outer waterproof layers 5. The thickness of the oil-proof layer 6 is 8-15 nm.
[0028] When manufacturing the utility model, the actual steps are as follows:
[0029] The first step is to select a polarizing film (2) with a polarization efficiency of 80%-85%. After bending the polarizing film (2), peel it off. Before peeling, clean the work surface and use tape to remove any rough edges and debris left after punching. Apply olive oil to both hands to prevent dandruff and debris, which also facilitates handling and prevents film slippage. Then, turn on the static air machine and ionizing fan to eliminate static electricity and prevent dust accumulation. Place the polarizing film (2) on a clean, dust-free cloth and gently wipe both sides clean. Using a fingertip cot on your index finger, peel the protective film off the polarizer. Gradually, using the grip, peel the front protective film first, then the back protective film (for adhesive-backed films, peel the adhesive side first, then the non-adhesive side). This process should be performed under an ionizing fan. Tilt the polarizing film (2) toward the light and carefully examine it. Gently wipe away any stains and debris from the surface with lens tissue dipped in isopropyl alcohol. Finally, trim the excess scraps from the handle neatly and cleanly, and carefully place the polarizing film 2 after tearing the film into the bracket of the dust-free fresh-keeping box.
[0030] The second step is to remove the polarizing film 2 from the dust-free box after tearing. Carefully inspect both sides for dust and stains. These can generally be removed with an air gun or gently wiped with lens tissue dampened with isopropyl alcohol. Align the four corners of the polarizing film 2 into the mold, ensuring it fits as closely as possible. Once again, check to ensure no dust has been introduced before closing the mold. Then, composite injection molding is performed with PA plastic rice to produce a PA nylon lens 1. The PA nylon lens 1 and polarizing film 2 combine to form a lens base layer 10, which is approximately 1.8-3.0 mm thick.
[0031] The third step is to use an automatic caustic soda machine to treat and clean the lens after the injection molding is completed to enhance the surface adhesion.
[0032] In the fourth step, two strengthening layers are applied to the inner and outer sides of the lens base layer 10 to form a composite strengthening layer 3. The composite strengthening layer 3 consists of a first strengthening layer 31 and a second strengthening layer 32. The first strengthening layer 31 is coated with an X4 strengthening solution, while the second strengthening layer 32 is coated with an X7 strengthening solution. The entire composite strengthening layer 3 has a thickness of 4-9 μm, making the lens wear-resistant and scratch-resistant.
[0033] The fifth step is to vacuum-deposit an anti-reflection film layer 4 on the inner surface of the inner composite strengthening layer 3. The thickness of the anti-reflection film layer 4 is 90-110 nm, which reduces the reflected light from the back of the lens to the eyes, making the vision clearer.
[0034] In the sixth step, a waterproof layer 5 is vacuum-deposited on the inner side of the anti-reflection film layer 4 to achieve waterproofing. The thickness of the waterproof layer 5 is 8-15 nm.
[0035] In the seventh step, a waterproof layer 5 is vacuum-deposited on the outer surface of the outer composite reinforcement layer 3 to achieve a waterproof effect. The thickness of the waterproof layer 5 is 8-15 nm.
[0036] In the eighth step, an oil-proof layer 6 is vacuum-deposited on the inner and outer surfaces of the inner and outer waterproof layers 5 to play an oil-proof role. The thickness of the oil-proof layer 6 is 8-15 nm.
[0037] At this point, the production of the nylon polarized lens of the utility model is completed.
[0038] This new pair of glasses combines a polarizing film 2 with a polarization efficiency of 80%-85% with a PA nylon lens 1. The low polarization rate allows the lens base layer 10 to still filter out some light from specific directions, providing a relatively clearer field of vision and reducing eye fatigue. Furthermore, because screen light is not completely filtered out, when viewing an LCD screen, the screen only dims slightly, but the content displayed on the screen is still easily visible. For cars equipped with head-up displays, wearing these glasses provides a clearer visual experience. This demonstrates that this new pair of glasses is a new type of polarized lens that allows for clear viewing of head-up displays and is suitable for driving.
[0039] The utility model adopts a two-layer composite strengthening layer 3 with a special structure to firmly combine the polarizing film 2 and the anti-reflection film layer 4, ensuring the wear and scratch resistance of the lens. The anti-reflection film layer 4 can reduce the reflected light on the back of the lens to the eyes, making the vision clearer. The composite strengthening layer 3 can ensure that the lens passes the aging test, so that the product meets the requirements of GB39552.1-2020 sunglasses and sun lenses.
[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the design of this case. Any equivalent changes made based on the key design of this case shall fall within the scope of protection of this case.
