There is also the service life of glasses, whether they are worn, whether they are worth replacing, and so on. Sometimes there are activities in the optical shop, and it is more appropriate to buy a new pair of glasses than a new pair of frames. Moreover, to change the frame, it is necessary to find the original lens shape, which is not only difficult to find, but also expensive and uneconomical.

Maintenance of spectacle frame
Keep clean: Sweat or grease on the skin can easily corrode the metal parts of glasses frames. Cleaning glasses every day is very helpful to prolong the life of glasses.
Avoid sunlight: keep it in a place where sunlight is easy to shine for a long time, because the frame is easy to fade under the decomposition of light and heat.
Wipe the glasses correctly: dry them with a special cloth for glasses. Don't touch the lens with hard objects. Don't wipe the lens with your fingers. Please wipe with a clean lens cloth to reduce lens wear.
Proper storage: Don't put the lens face down. When not in use, try to put it in the glasses case. When not in use, please wrap the glasses with mirror cloth and put them in the glasses case to avoid damage. ?
