The first slot has a first opening, and the first magnetic member 13 is inserted into the first slot through the first opening. Moreover, the end face of the first magnetic member 13 facing the second magnetic member 24 is substantially flush with the first opening; and / or, the lens frame 23 is provided with a second slot (not shown in the figure). The second slot has a second opening, and the second magnetic member 24 is inserted into the second slot through the second opening. Moreover, the end face of the second magnetic member 24 facing the first magnetic member 13 is substantially flush with the second opening.

[0047] In this embodiment, the end face of the first magnetic member 13 facing the second magnetic member 24 is substantially flush with the first opening, and the end face of the second magnetic member 24 facing the first magnetic member 13 is substantially flush with the second opening, which can improve the flatness and aesthetics of the lens frame 23 and the spectacle frame 11.

[0048] In one embodiment, please refer to Figure 2 and Figure 7 The spectacle frame 11 is provided with a first limiting member 111, and the lens frame 23 is provided with a second limiting member 231 that cooperates with the first limiting member 111. One of the first limiting member 111 and the second limiting member 231 is a limiting groove, and the other is a limiting block. The limiting block is inserted into the limiting groove. In this embodiment, the first limiting member 111 and the second limiting member 231 can limit and fix the lens frame 23, improving the installation firmness of the lens frame 23.

[0049] Furthermore, the spectacle frame 11 has a first edge 112, and the lens frame 23 has a second edge 232.
