Protection of Eyeglasses 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 and put them on along the two sides of the cheek in a parallel direction. 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. You need to hold the edge of the frame on one side of the glasses and gently wipe the lenses to avoid excessive force causing damage to the frame or the lenses.4. When not wearing your glasses, please wrap them in the case with the lens cloth and place them in the case. If you need to temporarily store them, please place the convex side of the glasses up, or the lenses may be easily scratched. At the same time, glasses should be avoided from contact with corrosive items such as insect repellent, toilet cleaning products, cosmetics, hair spray, and drugs, and should not be placed under direct sunlight or high temperature over 60℃ for a long time, otherwise it may cause degradation, deterioration, or color change of the lenses and frames. 5. Regular adjustment and shaping at professional stores are necessary. The deformation of the frame will cause burden on the nose and ears, and the lenses may also be easily loose. 6. Please do not use your glasses during intense sports to avoid strong impact leading to broken lenses, causing damage to your eyes and face. Do not use worn lenses to prevent light deviation causing vision decline. Do not look directly at the sun or strong light, to avoid harm to your eyes. 7. Maintenance of sunglasses The dazzling sunglasses let you be active in the sun, free and easy. In fact, sunglasses can block the sun, but they can't block the damage of pollution, so you need to care carefully to avoid embarrassment.In fact, the method of maintaining sunglasses is similar to maintaining ordinary glasses, including cleaning, folding, and storing them. However, since sunglasses are often taken off and put on, it is easy to scratch them accidentally, so there are some small details that need to be particularly reminded: when there are stains on the sunglasses, do not scratch them with your nails, which is easy to scratch the surface. When you do not wear sunglasses, many people will hang them on their heads, neck, or pockets, at this time, the body's movement should not be too large to avoid breaking or tearing. Some people will put them into their handbags, but we suggest that you first put them into a hard eyeglass case, and then put them into your handbag, to avoid being worn by small items such as keys, combs, coins, or contaminated by cosmetics such as lipstick.
