[0017] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0018] Please refer to Figures 1 to 3 , Figure 1 This is a cross-sectional schematic diagram of the lens and frame according to one embodiment of the present invention; Figure 2 This is a schematic diagram of a lens according to one embodiment of the present invention; Figure 3 This is a schematic diagram of a lens according to one embodiment of the present invention.

[0019] A protective and impact-resistant resin lens includes: a lens 1; the edge of the lens 1 is ground into an installation bevel 2 by a grinding device, the bevels 2 on both sides facilitate the lens 1 to be inserted into the mounting groove 4 of the frame 3, a plurality of slots 5 are provided around the edge of the lens 1, and shock-absorbing pads 6 are provided in the slots 5. The shock-absorbing pads 6 are made of silicone rubber, which has good elasticity, tensile strength, compression deformation, tensile strength, etc., and can maintain shape stability and restore its original shape under different external forces; the inner edge of the bevel 2 is transitioned to the surface edge of the lens 1 through an arc surface 7, the smoothness of the arc surface 7 can reduce hard contact with the frame 3.

[0020] The depth of the slot 5 is less than the thickness of the shock-absorbing pad 6. The shock-absorbing pad 6 is higher than the top surface of the slot 5. The shock-absorbing pad 6 is located between the lens slot 5 and the frame mounting slot 4. When the glasses are dropped, the shock-absorbing pad 6 can buffer and reduce the impact between the edge of the lens 1 and the frame 3, reducing the probability of damage.

[0021] The wear-resistant layer consists of a silicon oxide film layer 8, a zirconium oxide film layer 9, a titanium oxide film layer 10, a zirconium oxide film layer 9, and a titanium oxide film layer 10 in sequence from the inside to the outside. The lens 1 is first immersed in a prepared silicon oxide solution by dip-coating, then taken out and dried to form a silicon oxide film layer 8. Then, the surface is successively coated with a zirconium oxide film layer 9 and a titanium oxide film layer 10 by vacuum evaporation.

[0022] The wear-resistant layer consists of a zirconium oxide film layer 9, a titanium oxide film layer 10, a zirconium oxide film layer 9, a silicon oxide film layer 8, a zirconium oxide film layer 9, and a titanium oxide film layer 10, arranged sequentially from the inside out. The lens 1 is first coated with zirconium oxide film layer 9 and titanium oxide film layer 10 sequentially by vacuum evaporation, then immersed in a prepared silicon oxide solution by immersion coating, and then dried to form silicon oxide film layer 8. Finally, zirconium oxide film layer 9 and titanium oxide film layer 10 are coated sequentially by vacuum evaporation.
