Description

Technical Field

[0001] This utility model belongs to the field of lenses, specifically, it relates to an enhanced polarized lens. Background Technology

[0002] With the increasing popularity of outdoor activities and reliance on electronic devices, polarized lenses must simultaneously address multiple challenges, including glare interference, harmful blue light radiation, mechanical impact, and the corrosive effects of complex environments. Traditional polarized lenses often focus on a single function, such as eliminating scattered glare solely through a polarizing layer or filtering some blue light using a dyeing process, resulting in functional fragmentation and poor spectral selectivity. In existing technologies, blue light filtering layers often rely on organic dyes, which are susceptible to photodegradation under ultraviolet radiation, leading to a significant decline in protective performance over time. Furthermore, lens layers are often connected using physical bonding or ordinary adhesives, resulting in low interfacial bonding strength and a tendency to delaminate under temperature or humidity changes, affecting optical consistency. In terms of impact resistance design, conventional solutions use homogeneous polymer buffer layers, whose single porosity structure makes it difficult to balance energy absorption and stress dispersion: high-porosity layers are flexible but lack rigidity, while low-porosity layers are resistant to pressure but prone to brittleness. Such designs are prone to stress concentration under high-speed impacts, with impact energy absorption rates of less than 40%, leading to lens breakage. Meanwhile, the surface protection of the lenses is generally weak, and the hardness of the anti-scratch layer is mostly lower than 3H. Long-term use can easily cause scratches, and the lack of hydrophobic and anti-fog functions leads to blurred vision in rainy or temperature-different environments, which limits the user experience. Utility Model Content

[0003] In view of this, the technical problem to be solved by this utility model is to provide an enhanced polarizing lens. Traditional polarizing lenses have problems such as limited functionality, easy scratching, and insufficient impact resistance.

[0004] To solve the above-mentioned technical problems, this utility model discloses an enhanced polarizing lens, comprising: a substrate layer, an anti-fog and anti-fouling layer on the inner side of the substrate layer; a blue light filter layer on the outer side of the substrate layer, a polarizing layer on the outer side of the blue light filter layer, an impact-resistant buffer layer on the outer side of the polarizing layer, the porosity of the impact-resistant buffer layer gradually decreasing from 30% to 10% from the inner side to the outer side, a first serrated surface formed on the outer surface of the impact-resistant buffer layer, a high refractive layer on the outer side of the impact-resistant buffer layer, a second serrated surface forming at the bottom of the high refractive layer that engages with the first serrated surface, and a scratch-resistant hardening layer on the outer side of the high refractive layer.

[0005] According to one embodiment of the present invention, the refractive index of the high-refractive layer is 1.64-1.75.

[0006] According to one embodiment of the present invention, the scratch-resistant hardening layer is a polyurethane layer and the blue light filter layer is a cerium oxide layer.

[0007] According to one embodiment of the present invention, the depth of a single tooth on the first and second sawtooth surfaces is 0.05-0.5 mm, and the tooth pitch is 0.1-1 mm.

[0008] According to one embodiment of the present invention, the above-mentioned substrate layer, blue light filter layer, polarization layer, impact-resistant buffer layer, high refractive layer and scratch-resistant hardening layer are integrally formed by bonding with UV-curable adhesive.

[0009] Compared with the prior art, the present invention can achieve the following technical effects:

[0010] 1) By setting the porosity variation of the impact-resistant buffer layer, the impact energy is absorbed step by step, reducing stress concentration; by setting the first and second sawtooth surfaces to interlock, the bonding strength between the high refractive layer and the impact-resistant buffer layer is enhanced, preventing interlayer peeling; by setting the anti-fog and anti-fouling layer, blue light filter layer, polarization layer, impact-resistant buffer layer, high refractive layer and scratch-resistant hardening layer, multiple protections are provided, thereby achieving all-scene protection.

[0016] The following will describe in detail the implementation of this utility model with reference to the accompanying drawings and embodiments, so that the implementation of this utility model can be fully understood and carried out based on how technical means are used to solve technical problems and achieve technical effects.

[0017] Please refer to Figure 1 , Figure 1 This is a cross-sectional schematic diagram of an enhanced polarizing lens according to an embodiment of the present invention. As shown in the figure, an enhanced polarizing lens includes: a substrate layer 10, and an anti-fog and anti-fouling layer 20 provided on the inner side of the substrate layer 10.

[0018] In one embodiment of this utility model, the substrate layer 10 is made of polycarbonate optical resin with a thickness of 1.0-1.5 mm and a light transmittance of more than 99%. The anti-fog and anti-fouling layer 20 is a silicon dioxide layer. The anti-fog liquid is uniformly coated on the inner side of the substrate by spin coating to form a hydrophobic surface and improve the lens's anti-fog and anti-fouling capabilities.

[0019] Furthermore, a blue light filter layer 30 is provided on the outer side of the substrate layer 10, and a polarization layer 40 is provided on the outer side of the blue light filter layer 30.

[0020] In detail, a blue light filter layer 30 is provided on the outside of the substrate layer 10. The blue light filter layer 30 is a cerium oxide layer, which can effectively block more than 99% of harmful blue light. The polarization layer 40 is a PVA polarization film with a polarization efficiency greater than 99%.

[0021] Preferably, an impact-resistant buffer layer 50 is provided on the outer side of the polarization layer 40. The porosity of the impact-resistant buffer layer 50 gradually decreases from 30% to 10% from the inner side to the outer side. A first serrated surface 60 is formed on the outer surface of the impact-resistant buffer layer 50. A high-refractive-index layer 70 is provided on the outer side of the impact-resistant buffer layer. A second serrated surface 80 is formed at the bottom of the high-refractive-index layer 70 and engages with the first serrated surface 60.

[0022] Furthermore, an impact-resistant buffer layer 50 is provided on the outside of the polarization layer 40. The impact-resistant buffer layer 50 adopts a porous structure with a porosity that gradually decreases from 30% on the inside to 10% on the outside, combined with a micropore distribution with a pore size of 5-50 μm and a micropore distribution density that decreases from the inside to the outside, thereby achieving stepwise absorption of impact energy. The high-refractive-index layer 70 and the impact-resistant buffer layer 50 are connected by a first serrated surface 60 and a second serrated surface 80. The first serrated surface 60 and the second serrated surface 80 are formed by laser micro-engraving on the inner surface of the high-refractive-index layer 70 and the outer surface of the impact-resistant buffer layer 50. The depth of a single tooth on the first serrated surface 60 and the second serrated surface 80 is 0.05-0.5 mm, and the tooth pitch is 0.1-1 mm, thereby enhancing the bonding strength between the high-refractive-index layer 70 and the impact-resistant buffer layer 50 and preventing interlayer delamination.

[0023] In addition, the high refractive index of the high refractive layer 70 is 1.64-1.7, and the light transmittance reaches more than 98%, resulting in clear vision without distortion.

[0024] The high-refractive layer 70 of this invention has a scratch-resistant hardening layer 90 on its outer side. The scratch-resistant hardening layer 90 is a polyurethane layer with a surface hardness ≥5H, thereby enhancing the hardness of the outer surface of the lens.

[0025] Preferably, the substrate layer 10, blue light filter layer 30, polarizing layer 40, impact-resistant buffer layer 50, high refractive layer 70 and scratch-resistant hardening layer 90 are integrally formed by bonding with UV-curable adhesive, and the optical properties and structural stability are ensured by UV-curable adhesive.

[0026] In summary, this utility model achieves gradual absorption of impact energy and reduces stress concentration by setting a change in the porosity of the impact-resistant buffer layer 50; and enhances the bonding strength between the high-refractive-index layer 70 and the impact-resistant buffer layer 50 by setting a first serrated surface 60 and a second serrated surface 80 for interlocking connection, thereby preventing interlayer delamination.
