Description

Technical Field

[0001] This utility model belongs to the field of lens technology, specifically relating to a 3D printed lens. Background Technology

[0002] Most existing eyeglass lenses are made of resin. Opticians typically purchase large quantities of lenses of different prescriptions in advance. This advance purchasing method increases costs and easily leads to the accumulation of unsold, less frequently used lenses, hindering rapid cash flow. While the rapid development of 3D printing technology in recent years allows for the rapid creation of lenses with the required prescription, limitations in printing precision result in micro-depressions on the surface of the printed lenses, making them relatively rough and unsuitable for direct application to eyeglasses. Therefore, based on the shortcomings of existing technology, we propose a new 3D-printed lens. Utility Model Content

[0003] The purpose of this invention is to address the limitation of existing 3D-printed lenses that cannot be directly applied, and to propose a new type of 3D-printed lens. This 3D-printed lens undergoes effective surface treatment, enabling its efficient application in eyeglass assembly.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design a 3D printed lens, including a lens body, which is printed by a high-precision 3D printer. The inner side of the lens body is provided with an inner resin spraying layer, and the inner side of the inner resin spraying layer is polished to form an inner polishing layer.

[0006] The outer side of the lens body is polished to form a first polishing layer. A functional coating is provided on the outer side of the first polishing layer. An outer resin spraying layer is provided on the outer side of the functional coating. The outer side of the outer resin spraying layer is polished to form an outer polishing layer.

[0007] Furthermore, the inner resin coating layer and the outer resin coating layer are formed between the lens body and the same transparent resin material by spraying.

[0008] Furthermore, the functional coating is an anti-ultraviolet layer or an anti-blue light layer.

[0009] The 3D-printed lens proposed in this utility model has the following advantages: This utility model can quickly obtain the lens body of the required prescription through 3D printing. After effective surface treatment, the 3D-printed lens can be effectively applied to eyeglass assembly. Specifically, using the 3D-printed lens body as a carrier, resin spraying is applied to the lens body, forming inner and outer resin spraying layers on both sides of the lens body. This effectively fills the small depressions formed by 3D printing. Then, the inner and outer resin spraying layers are polished to remove excess spraying layer, making both sides of the lens body smooth and transparent, meeting the requirements for lens wear. Lenses formed through this rapid printing method can avoid the accumulation of purchasing lenses of different prescriptions in optical shops, reducing capital investment. In addition, this method allows for on-site customization of lenses, meeting the demand for customized eyeglass lenses. Attached Figure Description

[0017] The structural features of this utility model will now be described in detail with reference to the accompanying drawings.

[0018] See Figures 1-2 A 3D printed lens includes a lens body 1 made of resin. The lens body 1 is printed by a high-precision 3D printer. The power of the lens body 1 can be set by a computer, and the 3D printer can directly output the corresponding model according to the selected parameters. The printed lens body 1 has slight depressions on both sides, making its surface relatively rough. In order to eliminate the depressions on the surface of the lens body 1, an inner resin spray layer 2 is formed on the inner side of the lens body 1 by spraying. The inner resin spray layer 2 can fill the depressions formed on the inner side of the lens body 1, playing a repair role. On the other hand, it can increase the thickness of the inner surface of the lens body 1, which is convenient for subsequent grinding and polishing, so that the inner side of the lens body 1 will not be worn during polishing. After polishing, the inner side of the inner resin spray layer 2 forms an inner polishing layer 3. The polishing layer 3 is used to remove excess inner resin spray layer 2 and polish the inner side of the lens body 1 into a mirror structure.

[0019] The outer side of the lens body 1 is polished to form a first polishing layer 4. The function of the first polishing layer 4 is to form an uneven smooth surface on the outer side of the lens body 1. A functional coating 5 is provided on the outer side of the first polishing layer 4. The functional coating 5 is an anti-ultraviolet layer or an anti-blue light layer. The formation of the functional coating 5 on the uneven smooth surface on the outer side of the lens body 1 can increase the reflection or light absorption area and effectively scatter ultraviolet light, thus effectively improving the function of the functional coating 5. An outer resin spraying layer 6 is provided on the outer side of the functional coating 5. The outer resin spraying layer 6 is the same as the inner resin spraying layer 2. Both are formed by spraying transparent resin material with the lens body 1 to form a structure. The setting of the outer resin spraying layer 6 can fill the depressions formed by printing on the outer side of the lens body 1, playing a repair role. On the other hand, it can increase the thickness of the outer surface of the lens body 1, which is convenient for subsequent grinding and polishing, so that the outer side of the lens body 1 will not be worn during polishing. After polishing, the outer side of the outer resin spraying layer 6 forms an outer polishing layer 7. The outer polishing layer 7 is used to remove excess outer resin spraying layer 6 and to polish the outer side of the lens body 1 into a mirror structure.

[0020] This utility model discloses a 3D printed lens. The lens body 1 of the required prescription can be quickly obtained through 3D printing. Using the lens body 1 as a carrier, resin is sprayed onto both the inner and outer surfaces of the lens body 1, forming an inner resin coating layer 2 and an outer resin coating layer 6 on both sides. The inner and outer resin coating layers 2 and 6 effectively fill any small depressions on both sides of the lens body 1. Then, the inner and outer resin coating layers 2 and 6 are polished to remove excess coating, making both sides of the lens body 1 smooth and transparent, meeting the requirements for lens wear. This rapid printing method avoids the need for optical shops to purchase and accumulate lenses of different prescriptions, reducing capital investment. Furthermore, this method allows for on-site lens customization, meeting the demand for customized eyeglass lenses.

[0021] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
