[0003] In addition to using different glasses for vision correction in the medical field, there are also more diverse glasses on the market to meet different usage needs of people. Sometimes, when people lie in bed watching TV, playing with mobile phones, or reading books, they need to bend their necks to see the things below, which interferes with each other in the two states of rest and entertainment, causing certain inconveniences. And maintaining the state of bending the neck for a long time will strain the cervical spine and is not conducive to health. Therefore, there has emerged a type of glasses that can change the incident direction of light, which can directly view the lower field of vision after wearing, and is called "lazy glasses". However, this kind of "lazy glasses" maintains the basic structure of glasses, with a frame, temple arms, and lenses, and ordinary people can wear them casually.

[0041] Please refer to Figure 1 and Figure 2 , as a further implementation of the movable leg: protective sleeves 19 are provided on both the fixed leg 8 and the movable leg 7.

[0042] Specifically, the lower parts of both the fixed leg 8 and the movable leg 7 are provided with protective sleeves 19. The protective sleeves 19 contact the spectacle frame. And the protective sleeves 19 are made of rubber, with better protection effect, avoiding scratching the spectacle frame and the user by the metal material, making the wearer more comfortable.

[0043] In summary, when the overall device is in use or operation:

[0044] When using the device, it is supported by the support base 1. When applying pressure to the pressure head 10, the thumb of the user's hand contacts the pressure head 10, while the other parts of the hand contact part of the pressure block 16. The rotation of the pressure head 10 can be easily controlled with only one hand. Under the fixation of the rotating ear 5, the pressure head 10 drives the normal rotation of the rotating shaft 6. Through the conduction of the rotating shaft 6, the movable legs 7 at both ends rotate. Through the cooperation of the movable legs 7 and the fixed legs 8, the distance between the movable legs 7 and the fixed legs 8 becomes larger, clamping the spectacle frame worn by the user. And after releasing the pressure head 10, the torsion spring 9 provides pressure, causing the pressure head 10 to drive the movable legs 7 to rotate back. Thus, under the cooperation of the movable legs 7 and the fixed legs 8, the spectacle frame is clamped, installing the device on the spectacle frame. And when wearing, the lower parts of the fixed legs 8 and the movable legs 7 will contact the spectacle frame through the protective sleeves 19, and the protective sleeves 19 are made of rubber, with better protection effect, avoiding scratching the spectacle frame and the user by the metal material, making the wearer more comfortable.

[0045] After installing the device on the spectacle frame, the support base 1 is used as the central support for the overall device. Through the connection of the support frame 2, the mounting brackets 3 at both ends are supported. The refraction prism 4 is supported by the mounting brackets 3. After installation, the refraction prism 4 will be aligned with the lens part of the spectacle frame being worn, providing the function of refracting light. In addition, the mounting bracket 3 is composed of the cooperation of the prism bracket 13 and the connecting bracket 14, making the mounting bracket 3 present an L shape, so that the installation direction of the support frame 2 and the refracting direction of the refraction prism 4. If the structure of the device does not match the spectacle frame being worn, the fixing nut 12 can be loosened to release the fixation of the fixing bolt 11 and the fixing nut 12 on the mounting bracket 3 and the support frame 2. Then, the fixing bolt 11 slides in the long through hole 15 to adjust the position of the fixing bolt 11, thereby adjusting the mating position of the support frame 2 and the mounting bracket 3 to align the refraction prism 4 with the lens structure. Then, it is fixed under the cooperation of the fixing nut 12 and the fixing bolt 11 to complete the adjustment of the structure and ensure the usage experience of the wearer. In addition, through the restriction and guidance of the guide frame 17, the rotating shaft 6 is made more stable, and through the cooperation of the reinforcing block 18 and the support base 1, the fixation of the support frame 2 is strengthened to ensure the stability of the support frame 2.
