TECHNICAL FIELD

[0001] The utility model belongs to glasses technical field relates to a spectacle lens. BACKGROUND

[0002] Glasses are common optical devices in the prior art, which are mainly composed of two parts of lens and frame. In terms of its use, it can be roughly divided into myopia glasses, hyperopia glasses, astigmatism glasses, flat light glasses, goggles, night vision glasses, sunglasses and sunglasses, etc.

[0003] But unlike myopia glasses, hyperopia glasses and astigmatism glasses, sunglasses and sunglasses of the same type are not used to correct and improve vision, but to filter part of the light to achieve the effect of protecting the user's eyes to ensure the comfort of the user's eyes in strong light weather.

[0004] The specific structure of the spectacle lens is the most important factor in achieving the above effect. In the prior art, the spectacle lens assembled for the above-mentioned glasses with protective effect is often formed by stacking multiple material layers. Specifically, it generally includes a base layer made of resin material, and an ultraviolet absorbing layer (made of polycarbonate material) formed on the lower surface of the base layer under high temperature and high pressure. In order to ensure the overall structural strength of the composite spectacle lens, a reinforcing layer made of glass material (surface coated with alloy film) is usually fixed on the upper surface of the base layer and the lower surface of the ultraviolet absorbing layer.

[0005] However, in actual situations, light with high brightness also generally has high temperature. Although the light is filtered by the base layer and the ultraviolet absorbing layer, the red light contained in the light cannot be effectively treated, and directly acts on the user's eyes after passing through each level of the spectacle lens, which has poor heat insulation effect, and the user's eyes have obvious burning sensation, which will cause certain damage to the user's eyes. SUMMARY

[0006] The utility model aims at the above-mentioned problems existing in the prior art, and proposes a kind of, the technical problem to be solved by the utility model is: how to improve the heat insulation effect of spectacle lens.

[0007] The purpose of the utility model can be realized by the following technical scheme: a spectacle lens, including the base layer made of resin material, characterized in that, the upper surface of the base layer has the upper ice muscle layer made of silica aerogel material, and the lower surface of the base layer has the lower ice muscle layer made of silica aerogel material.

[0008] The base layer made of resin material is the prior art, in addition, in order to solve the burning discomfort of the user's eyes caused by the light penetrating the base layer under strong light conditions in the prior art, the ice muscle layer, i.e. the upper ice muscle layer and the lower ice muscle layer, is arranged on both sides of the base layer, which is specifically silica aerogel, also known as silica porous air gel material. In natural light, infrared light often carries the main heat. When in use, the external natural light can first penetrate the upper ice muscle layer, and the infrared light and other visible light in the natural light are reflected and absorbed by the material characteristics of the upper ice muscle layer, so as to preliminarily isolate the heat and reduce the heat transfer. The natural light filtered preliminarily is filtered again by the lower ice muscle layer through the base layer, so that the infrared light in the natural light is consumed and reflected and dispersed by the two layers of ice muscle layers, thereby reducing the heat conduction, and the burning discomfort is reduced when the light penetrates the lens and acts on the user's eyes, and the heat insulation effect of the lens is effectively improved.

[0009] In the above, the thickness of the upper ice muscle layer and the lower ice muscle layer is between 0.1-0.2mm. The filtering performance of the upper ice muscle layer and the lower ice muscle layer to natural light can be optimized, and the difficulty of molding and the overall thickness of the lens can be avoided due to the excessive thickness of the two layers.

[0010] In the above, the lens further comprises a polarizing layer made of nylon material, which is formed on the upper surface of the base layer, and the upper ice muscle layer is formed on the polarizing layer. The setting of the polarizing layer is to exclude and filter the scattered light in the light after the natural light is filtered by the upper ice muscle layer, so that the natural light is softer, and the polarizing layer is often formed together with the base layer in the prior art. By forming the upper ice muscle layer on the polarizing layer, the original lens can be improved, thereby reducing the cost of research and development.

[0011] In the above, the lower surface of the lower ice muscle layer is formed with a reflection-reducing layer made of calcium fluoride material. The setting of the reflection-reducing layer can avoid the reflection of the natural light after being filtered by the lower ice muscle layer, thereby preventing the mirror effect and the existence of virtual image, and playing a protective role on the lower ice muscle layer.

[0012] In the above, the upper surface of the upper ice muscle layer has a solidification layer made of glass material with hard alloy plated on the surface. By setting the solidification layer, the hardness and wear resistance of the outer surface of the lens are improved, and the structure strength of the lens is ensured while playing a protective role on the upper ice muscle layer.

[0013] Compared with existing technologies, this technology has the following advantages: By setting up upper and lower ice-skin layers, natural light is filtered twice when it passes through the lens, which consumes and reflects the infrared light in the natural light, reduces heat conduction, and ensures that the burning discomfort is reduced when the light passes through the lens and acts on the user's eyes, thus effectively improving the heat insulation effect of the lens.

[0015] In the diagram, 1 is the base layer; 2 is the upper ice-textured layer; 3 is the lower ice-textured layer; 4 is the polarizing layer; 5 is the anti-reflection layer; and 6 is the curing layer. Detailed Implementation

[0016] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0017] like Figure 1 As shown, this eyeglass lens includes a base layer 1 made of resin material, a polarizing layer 4 made of polyvinyl alcohol material, an upper ice-textured layer 2 and a lower ice-textured layer 3 made of silica aerogel material, a curing layer 6 formed by plating a hard alloy onto the glass surface, and an anti-reflective layer 5 made of calcium fluoride. The thickness of the base layer 1 and the curing layer 6 is between 0.1 and 0.5 mm, while the thickness of the upper ice-textured layer 2, the lower ice-textured layer 3, the polarizing layer 4, and the anti-reflective layer 5 is between 0.1 and 0.2 mm. However, the thickness of the base layer 1 and the curing layer 6 is greater than the thickness of the ice-textured layer, the lower ice-textured layer 3, the polarizing layer 4, and the anti-reflective layer 5.

[0018] like Figure 1 As shown, the polarizing layer 4 is attached to the upper surface of the base layer 1 under high temperature and high pressure in a vacuum environment. The upper ice-textured layer 2 is attached to the upper surface of the polarizing layer 4 under high temperature and high pressure in a vacuum environment. The curing layer 6 is bonded to the upper surface of the upper ice-textured layer 2 with adhesive. The lower ice-textured layer 3 is attached to the lower surface of the base layer 1 under high temperature and high pressure in a vacuum environment. The anti-reflection layer 5 is attached to the lower surface of the lower ice-textured layer 3 under high temperature and high pressure in a vacuum environment.

[0019] When the eyeglasses are used by the user by combining the eyeglass lens and the frame, the natural light from the outside enters the eyes after passing through the curing layer 6, the upper ice muscle layer 2, the polarizing layer 4, the base layer 1, the lower ice muscle layer 3 and the anti-reflection layer 5 in sequence. In the process, the curing layer 6 mainly plays a protective role to avoid the internal layers from being worn by contacting with other objects. When the light passes through the upper ice muscle layer 2, the infrared light and part of the visible light are absorbed and reflected. Then the scattered light in the light is filtered through the polarizing layer 4. After passing through the base layer 1, the light is filtered again by the lower ice muscle layer 3, so that the infrared light energy in the light is reduced to the minimum. Finally, the light acts on the eyes of the user after passing through the anti-reflection layer 5, thereby achieving the effect of sufficient heat insulation.

[0020] The specific embodiments described herein merely exemplify the spirit of the present application. Those skilled in the art to which the present application pertains can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, without departing from the spirit of the present application or exceeding the scope defined by the appended claims.

[0021] Although the terms such as the base layer 1, the upper ice muscle layer 2, the lower ice muscle layer 3, the polarizing layer 4, the anti-reflection layer 5 and the curing layer 6 are used more frequently herein, the possibility of using other terms is not excluded. These terms are used only for more conveniently describing and explaining the essence of the present application; any kind of additional limitation by interpreting them is contrary to the spirit of the present application.
