Description

Technical Field

[0001] The utility model relates to the technical field of optical lenses, and specifically relates to a high heat-resistant optical lens. Background Technique

[0002] A lens is a transparent material with one or more curved surfaces made of optical materials such as glass or resin. After being polished, it is often assembled with a spectacle frame to form glasses, which are used to correct the vision of users and obtain a clear field of view.

[0003] For example, the published document with the application number 202322282702.0 discloses a solution to the problem that the lens body and the main body of the spectacle lens of the existing myopia prevention and control microlens spectacle lens do not have an electromagnetic wave shielding layer and a blue light shielding layer, making it difficult to shield harmful electromagnetic waves and blue light. At the same time, affected by light interference, long-term wearing will cause discomfort to the eyes. However, when this lens is worn under direct sunlight outdoors, the light source shines directly on the lens for a long time, causing the lens to heat up by itself, which will accelerate the aging and damage process of the lens. At the same time, the direct light source will also directly penetrate the lens and stab the human eye, resulting in strong light blindness and affecting wearing comfort.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structural deficiencies, and a high heat-resistant optical lens is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a high heat-resistant optical lens to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A high heat-resistant optical lens, including lens one, a lens two is fixedly arranged at the rear side of the lens one, a cavity is arranged in the middle of the lens one and the lens two, a rubber ring is fixedly arranged on the surface of the joint of the lens one and the lens two, and polarizing films are fixedly installed on the outer sides of the surfaces of the lens one and the lens two.

[0007] Preferably, the shape of the lens one is set as a "C" shape, and the lens two is also set as a "C" shape opposite to the lens one in the reverse direction.

[0008] Preferably, the cavity is formed by the middle groove body after the "C" shaped cross plates of the lens one and the lens two are combined, and the cavity is a vacuumed cavity.

[0009] Preferably, the rubber ring is a soft nitrile rubber, and the rubber ring is coated in the middle of the joint of the lens one and the lens two and is fixedly connected to both the lens one and the lens two.

[0010] Preferably, a hydrophobic film is fixedly adhered to the front side of the surface of the polarizing film on one surface of the lens, and the hydrophobic film is a polymer film made of a mixture of polytetrafluoroethylene, polyethylene and polypropylene.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The utility model can greatly improve the heat resistance of the lens as a whole and the comfort of wearing the lens by setting the cavity and the polarizing film, and reduce the damage to the human eye caused by the direct light source. The temperature change of the lens itself is small and the heat resistance is high, so that when the temperature changes, the lens surface is not easy to generate fog, and the weight of the entire lens is reduced;

[0013] 2. The utility model provides a rubber ring and a hydrophobic film. The rubber ring can improve the sealing of the joint between the first lens and the second lens after assembly, thereby preventing air from leaking into the cavity and causing vacuum failure. The rubber ring is convex all around, and when the lenses are assembled, it can provide a certain barrier and buffer between the lenses and the grooves of the assembly parts to prevent lens wear. The hydrophobic film is located on the front side of the lens. When the lenses are worn outdoors in rainy weather or humid spaces, it can prevent the outer side of the lenses from being contaminated by water droplets and causing blurred vision.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figure 1-Figure 3As shown in the figure, a high heat-resistant optical lens includes a first lens 1. A second lens 2 is fixedly arranged at the rear side of the first lens 1. A cavity 3 is arranged in the middle of the first lens 1 and the second lens 2. A rubber ring 4 is fixedly arranged on the surface of the joint of the first lens 1 and the second lens 2. Polarizing films 5 are fixedly installed on the outer sides of the surfaces of the first lens 1 and the second lens 2.

[0020] By adopting the above technical solution, the polarizing film 5 can reflect and refract light, so that only light with a specific polarization direction can pass through, while light in other directions is absorbed or reflected, thereby realizing precise control of light, reducing the direct irradiation of a large number of heat sources on the lens, making the degree of direct irradiation of the heat source received by the lens smaller under the same outdoor light irradiation intensity, and improving the heat resistance of the lens under the same outdoor light source temperature;

[0021] Reduce the overall cold and heat changes received by the lens, thereby avoiding the generation of fog on the lens surface.

[0022] Furthermore, the shape of the first lens 1 is set as a "C" shape, and the second lens 2 is also set as a "C" shape opposite to the first lens 1.

[0023] By adopting the above technical solution, the first lens 1 and the second lens 2 set in a "C" shape reduce the contact surface after assembly, thereby avoiding a large amount of heat transfer through the connection points.

[0024] Furthermore, the cavity 3 is formed by the middle groove body after the "C" - shaped cross - plates of the first lens 1 and the second lens 2 are combined and对接ed. The cavity 3 is a cavity pumped to a vacuum.

[0025] By adopting the above technical solution, the hollow cavity can completely block the transfer and absorption of heat, and further prevent the temperature from being transferred between the front and rear lenses.

[0026] Furthermore, the rubber ring 4 is a soft nitrile rubber. The rubber ring 4 is coated in the middle of the joint of the first lens 1 and the second lens 2 and is fixedly connected to both the first lens 1 and the second lens 2.

[0027] By adopting the above technical solution, the rubber ring 4 can improve the sealing performance of the joint after the first lens 1 and the second lens 2 are assembled, and avoid the situation that air leaks into the cavity 3 and causes vacuum failure; the rubber ring 4 protrudes around, and when the lens is assembled, it can provide a certain barrier and buffer to the groove body of the lens and the fitting, avoiding lens wear.

[0028] Furthermore, a hydrophobic film 6 is fixedly pasted on the front side of the surface of the polarizing film 5 on the surface of the first lens 1. The hydrophobic film 6 is a polymer film made of a mixture of polytetrafluoroethylene, polyethylene and polypropylene.

[0029] By adopting the above technical solution, it can avoid the situation that water droplets contaminate the outer side of the lens and cause blurred and blocked vision.

[0030] Working principle: When using the high heat-resistant optical lens, first, the lens 1 and the lens 2 2 are combined into a lens as a whole, and the frame assembly is assembled. The rubber ring 4 is protruding around. When the lens is assembled, it can provide a certain barrier and buffer between the lens and the groove of the assembly. After the assembly is installed and worn manually, when walking outdoors in strong light, the polarizing film 5 can reflect and refract the light, so that only the light in a specific polarization direction can pass through, while the light in other directions is absorbed or reflected, thereby achieving precise control of the light, thereby reducing a large amount of heat light sources from directly irradiating the lens, so that the lens can withstand the same outdoor light intensity. The degree of direct heat from the light source is smaller, the polarizing film 5 can also enable the wearer to maintain a clear field of vision without glare under the direct light source, and the cavity 3 is a hollow cavity, and the vacuum setting can completely block the transfer and absorption of heat, so that the temperature between the front and rear lenses cannot be transferred, and the weight of the entire lens is reduced. The temperature change of the lens itself is small and the heat resistance is high, so that when the temperature changes, the surface of the lens is not easy to fog up. Wearing the lens outdoors in rainy weather or humid space can avoid the blurred vision caused by water droplets on the outer side of the lens. This is the working principle of the high heat-resistant optical lens.
