Furthermore, in the following detailed description of the present invention, certain specific details are set forth in order to provide a better understanding of the present invention. It will be apparent to one skilled in the art that the present invention may be practiced without these specific details.

The spectacle frame provided with the interpupillary distance detection diagram on the simulation lenses as shown in fig. 1 to 3 comprises two spectacle frames 1 which are arranged along axial symmetry, a nose bridge 2 is arranged between the two spectacle frames 1, the two spectacle frames 1 are respectively provided with the same simulation lenses 3, and the simulation lenses 3 are made of transparent plastic materials. Two opposite sides of the two mirror frames 1 are respectively provided with a pile head 4 and a mirror foot 5.

As shown in fig. 1 and 3, the normal interpupillary distance is between 53mm and 73mm, but the normal interpupillary distance of each person is different according to gender, face size and shape, and eye socket. Therefore, in the present embodiment, the geometric center point of the simulated lens 3 is taken as the origin 6, and the distance between the origins 6 on the two simulated lenses 3 is set to be 50mm-70mm, i.e. the corresponding pupil distance represented by the simulated lens 3 is 50mm-70 mm. According to different sizes of human faces, the spectacle frame 1 can be set to different sizes, the length of the nose bridge 2 is set to be 15mm-20mm, the length of the spectacle legs 5 is set to be 130mm-150mm, and when a patient wears the spectacle, the patient can select a spectacle frame suitable for the patient to wear.
