Check your glasses

1. Frame size (emphasis)

2. Check whether the parts of the glasses are missing. (frame, pile head, mirror foot, foot cover, hinge, lock block, screw, nose rest)

3. Check whether the screws are too tight or too loose. (at the bridge cover/foot/frame)

4. Check if the earhooks are too tight or too loose.

5. Check the frames and frames for scratches, cracks and stains.

6. Check the assembly of glasses for errors.

7. Check whether the lens is firm.

8. Check whether the LOGO printing is clear and there is no double image.

9. Check the lens for scratches, damages, stains and cracks.

10, check the frame material, there is no defect, whether easy to break.

11. Check whether the surface is painted evenly and the color is bright.

12. Check whether the bridge sleeve has any unrepaired corners.

13. Check whether the hooks on both sides are symmetrical and smooth. (it is better to choose a flat and clean place, open the glasses and place them horizontally to check whether the height of the hooks on both sides is the same and whether the structure is symmetrical.)
