  1. Levi glasssesStick non-slip nose pad

If it is a frame without nosepiece, there is no way to relieve it by adjusting the nosepiece, then we have to use nose pads to improve it.The better quality imported nose pads are mostly made of soft and transparent silicone, which is not easy to yellow and not easy to deform, and has strong anti-slip and corrosion resistance. And you can also choose different thin and thick nose pads according to your needs.
However, remember that nose pads cannot be reused and cannot be rinsed directly with water. For nose pads, they typically have a usage period of approximately 3 months. During summer when sweating is more frequent, it is advisable to replace them every two months. However, in winter when sweating is less, replacements can be made once every six months.

  1. Install an eyeglass anti-slip sleeve on the temples

Place the anti-slip sleeve on top of the temples and hook it over the ears without affecting the aesthetics. If you usually exercise and work out a lot, or engage in heavy work, you can consider adding a non-slip cover on the temples to avoid the glasses from slipping, but also to protect the frame from being broken.
There are many forms of anti-slip sleeves, invisible, anti-allergic, and simple ear hook forms, you can choose according to your needs.
