1. First, check whether the glasses are loose. If it is loose, please go to the nearby optical shop to find an optometrist to adjust it. Mom said: Professional people do professional things. Adjusting the picture frame is a very profound knowledge. Don't think that you can solve it with a screwdriver twice. 2. If the frame has a nose pad, the sliding phenomenon can be alleviated by adjusting the nose pad. Sliding or uneven glasses are basically caused by uneven weight, and adjusting the nose pad can make the frame tend to be balanced again. Of course, please go to the optical shop and ask the optometrist to adjust it. 3. If it is a frame without a nose pad, there is no way to adjust the nose pad to alleviate it, but you can choose to use the nose pad to improve it. The imported nose pads with good quality are mostly soft and transparent silicone materials, which are not easy to yellow and deform, and have strong anti-slip and corrosion resistance. And you can choose nose pads with different thicknesses according to your own needs. However, remember that the nose pad cannot be reused or directly washed with water. To do these two things well, the nose pad can basically be used for about 3 months, sweating a lot in summer, and it can be replaced once every two months; Sweat less in winter, just change it once every six months. 4. Put anti-slip sleeves on the temples. The anti-slip sleeve is placed on the temple and hooked on the ear, which does not affect the appearance. If you exercise regularly or engage in heavy physical labor, you can consider adding anti-slip sleeves at the temples to prevent the glasses from slipping and protect the frames from being broken!
