Cleaning and maintenance of reading glasses1. Cleaning:A. When the lens becomes dirty or contaminated with dust, do not wipe the lens with clothes or ordinary cloth, because the cloth with thick and hard fiber may produce mesh scars on the surface of the lens. Please clean it with our complimentary mirror cloth.B. If the lens is too dirty, it can also be washed with cold water. After washing the glasses with tap water, hold the edge of the frame or the cross beam with one hand, dip the clean thumb and index finger of the other hand with neutral cleaners such as medium alkaline soap or detergent, gently rub and wash them against both sides of the lens, and then rinse them with clean water, Then use cotton or paper towel with good texture or clean cloth distributed by us to absorb water2. Placement:A. If the glasses are placed temporarily, the convex surface of the glasses should be placed upward. If you place the glasses with the convex face down, the lenses will be worn.B. High temperature is easy to cause lens deformation or surface film cracks. Please do not put it in the front window of the cab and other places with direct sunlight and high temperature.3. Storage:A. If you don't wear it for a long time, don't put it in your bag or pocket. It's very easy to scratch the film. Instead, put it in the glasses bag / box with glasses cloth.B. Avoid contact with corrosive articles, otherwise it will cause lens deterioration, deterioration, discoloration and damage the film.
