The engagement or disengagement between the fastening block 3 and the groove 2 causes the groove 10 of the frame 1 to clamp or release the lens 4.

[0041] With the above structure, the lens 4 can be detached through the buckle groove 2 and the fastening block 3. The buckle groove 2 is integrated on the upper side 11 of the frame 1, and the fastening block 3 is pivotally connected above the nose pad 5 on the lower side 12 of the frame 1. The overall structure of the frame 1 is simple and compact, which will not affect the overall aesthetics of the frame 1. Moreover, the buckle groove 2 and the fastening block 3 are simple and lightweight, which will not cause a significant increase in the overall weight of the frame 1, and can effectively reduce the discomfort of the user when wearing it.

[0042] See Figures 4 to 11 This demonstrates the specific structure of the buckle groove 2 and the buckle block 3 in this embodiment.

[0043] The fastening part 30 of the fastening block 3 includes an upper fastening piece 301 and a lower fastening piece 302. When the fastening part 30 is fastened in the fastening groove 2, the upper fastening piece 301 and the lower fastening piece 302 are inserted into the fastening groove 2 and respectively clamped on the upper and lower sides of the step 21. When the fastening block 3 and the fastening groove 2 are fastened, they can be in an interference fit state, so that they are clamped after fastening, the entire frame 1 is positioned, and the groove 10 of the frame 1 is squeezed, so that the groove 10 clamps the lens 4 inserted therein.
