Maintenance Methods for Sunglasses/Steps Maintaining sunglasses is similar to maintaining regular glasses, including cleaning, folding, and storing them. However, since sunglasses are often taken on and off, they are easily scratched if not handled carefully. Therefore, there are some small details that need to be particularly reminded: when there are stains on the sunglasses, do not try to scratch them with your fingernails, as this is very easy to scratch the surface. When you are not wearing sunglasses, many people will casually hang them on their heads, necks, or pockets. At this time, do not move too much, or they may be pulled or damaged. Some people will put them in their handbags, but it is recommended that you first put them in a hard eyeglass case before putting them in your handbag, to avoid being worn by small items such as keys, combs, coins, or contaminated by cosmetics such as lipstick. For drivers who wear sunglasses, they often put them on the dashboard or seat when they are not wearing them. This is a very bad habit, as the hot weather will bake the sunglasses into an unrecognizable shape, especially for plastic frames, which are even worse. It is best to take them out of the car or store them in the eyeglass storage box. No matter where you store your sunglasses, remember to keep the lens facing up.
 
Notes
 
1. Wearing and taking off glasses with one hand can destroy the balance of the left and right sides of the frame, leading to deformation. It is recommended that both hands hold the legs of the glasses and take them off parallel to the cheeks. 2. Generally, you should fold the left leg of the glasses first when taking them off, which is less likely to cause frame deformation. 3. It is recommended to rinse the glasses with clean water and absorb the moisture with a paper towel, and then use a special glasses cloth to wipe. When wiping the side of the frame, you need to hold the edge of the frame gently, avoid excessive force to avoid damage to the frame or the lens. 4. When you don't wear glasses, please wrap them with a glasses cloth and put them in the glasses box. If you need to temporarily put them away, please put the convex side of the glasses up, or the lenses will easily be scratched. At the same time, glasses should be avoided from contact with corrosive items such as insect repellent, toilet cleaning products, cosmetics, hair spray, drugs, etc., and avoid long-term direct sunlight and high temperature.
