Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1:

[0028] like Figures 1-9 As shown, a high refractive index polarizing resin lens according to an embodiment of the present utility model includes a refractive component 1, and a protective component 2 is disposed on the outside of the refractive component 1.

[0029] The refractive component 1 includes a substrate 101, which is aspherical and can be configured as a concave lens or a convex lens depending on the application. Polarizing layers are symmetrically arranged at both ends of the substrate 101, and the polarizing layers are made of polyvinyl alcohol. A first refractive layer 102, a second refractive layer 103, and a third refractive layer 104 are sequentially arranged at both ends of the substrate 101. A fourth refractive layer 106 is arranged between the first refractive layer 102 and the second refractive layer 103.

[0030] The first refractive layer 102, the second refractive layer 103, the third refractive layer 104, and the fourth refractive layer 106 are respectively composed of a sulfur compound coating (such as 1,5-dithioheterocyclic octane-3-ol), a polyimide resin, a thiopolyurethane resin, and a nano-silica coating material.

[0031] Both the third refractive layer 104 and the substrate 101 are provided with a blue light blocking coating 105. The blue light blocking coating 105 is a CeO2 nano-coating used to absorb blue light, and the blue light blocking coating 105 is compatible with the third refractive layer 104 and the substrate 101.

[0032] Example 2:

[0033] like Figures 1-9 As shown, according to an embodiment of the present invention, a high refractive index polarizing resin lens includes a protective component 2 comprising an impact-resistant layer 201 made of polycarbonate. The impact-resistant layer 201 is disposed around a substrate 101, a first refractive layer 102, a second refractive layer 103, a third refractive layer 104, an anti-blue light coating 105, and a fourth refractive layer 106. Abrasion-resistant layers 202 are disposed at both ends of the impact-resistant layer 201. The abrasion-resistant layers 202 are nano-ceramic coatings, and the abrasion-resistant layers 202 and the impact-resistant layer are... The wear-resistant layer 202 is compatible with the anti-blue light coating 105 at one end. A protective coating 203 is provided around the wear-resistant layer 202 and the impact-resistant layer 201. The protective coating 203 is a benzotriazole coating. The impact-resistant layer 201 and the protective coating 203 are provided with a first connecting groove 3 and a second connecting groove 4 at equal distances to ensure the connection effect of the lens. The first connecting groove 3 and the second connecting groove 4 overlap to form a semicircle. The protective coating 203 is compatible with the wear-resistant layer 202 and the impact-resistant layer 201.

[0034] The connection relationships between the aforementioned impact-resistant layer 201, substrate 101, first refractive layer 102, second refractive layer 103, third refractive layer 104, fourth refractive layer 106, anti-blue light coating 105, wear-resistant layer 202, protective coating 203, and impact-resistant layer 201 are existing conventional technical means and processes, and therefore will not be described in detail.

[0035] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0036] In summary, with the help of the above-mentioned technical solution of this utility model, in the refractive component 1, the substrate 101 serves as the core structure. Its aspherical design allows it to be adjusted to a concave or convex lens according to actual needs, thereby optimizing the refraction effect of light. The polarizing layers at both ends of the substrate 101 are made of polyvinyl alcohol material, which can effectively filter stray polarized light, such as glare generated by reflection on a smooth surface, to improve visual clarity. The two ends of the substrate 101 are sequentially provided with a first refractive layer 102, a second refractive layer 103, and a third refractive layer 104. These three refractive layers, together with the fourth refractive layer 106 located between the first refractive layer 102 and the second refractive layer 103, work together to achieve precise control of light. These refractive layers are respectively composed of sulfur compound coating, polyimide resin, thiopolyurethane resin, and nano-silica coating material, ensuring the high refractive index characteristics of the lens, meeting the needs of people with high prescriptions for thin lenses, and ensuring good optical performance.

[0037] In the protective component 2, the impact-resistant layer 201 is made of polycarbonate and tightly wraps around the substrate 101 and the periphery of each refractive layer and the blue light blocking coating 105, providing strong impact protection for the lens. The two ends of the impact-resistant layer 201 are provided with abrasion-resistant layers 202, which are nano-ceramic coatings. They work together with the impact-resistant layer 201 to enhance the abrasion resistance of the lens and effectively prevent wear that may occur during daily use. One end of the abrasion-resistant layer 202 is in contact with the blue light blocking coating 105, further improving the protective performance of the lens. In addition, a protective coating 203 is provided around the abrasion-resistant layer 202 and the impact-resistant layer 201. The protective coating 203 is made of benzotriazole coating, which provides additional protection for the lens. The first connecting groove 3 and the second connecting groove 4, which are equally spaced on the impact-resistant layer 201 and the protective coating 203, overlap to form a semicircle. This not only helps to ensure the structural stability of the lens, but also optimizes the connection effect of the lens.

[0038] During use, the refractive component 1 and the protective component 2 work together. The refractive component 1 achieves a thinner and lighter lens while ensuring good optical performance, such as clarity and color reproduction, and reduces visual interference. This allows the wearer to have a comfortable visual experience in various lighting environments, such as driving, outdoor sports, or using electronic devices. The protective component 2 provides comprehensive protection for the lens, effectively preventing damage to the lens from external impacts, abrasions, and blue light, extending the lens's lifespan, and maintaining stable optical performance.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
