Most of the reasons why the screws on glasses are easy to fall off are caused by irregular wearing of glasses. Pay attention to holding the tail of the glasses legs with both hands, and take them off along the parallel and upward directions on both sides of the cheeks. If you take it off with one hand, the glasses will be deformed.
Pay attention to folding the glasses frame from the left. The glasses frames of mainstream manufacturers are designed by folding from the left temple, so if the right temple is folded first, it is easy to cause deformation or wear of the glasses frames. Placement method of glasses: When placing glasses temporarily, it is best to put the convex surface of glasses upward. If the convex surface is facing down, it is likely to scratch the lens.
Custody and maintenance of glasses;
When you don't wear glasses, please wrap them in glasses cloth and put them in the glasses case. Please avoid contact with insect repellent, toilet cleaning products, cosmetics, hair gel, medicines and other corrosive substances. When stored, otherwise it will cause deterioration, deterioration and discoloration of lenses and frames.
When the glasses are deformed, the deformation of the glasses frame will burden the nose or ears, which will lead to the change of the diopter of the lens and make the lens easy to loosen. It is recommended to go to a specialty store for plastic surgery regularly.
Do not leave the glasses at high temperature (above 60C) for a long time, which may easily lead to lens deformation or surface film cracking. Please do not put it in the front window of the cab and other places with direct sunlight or high temperature.
Please dry the lens immediately after it is wet. If it is dried naturally, the scale will become a stain, which is difficult to clean and will make things blurred. Sweat stains and cosmetic traces must be wiped clean. If the lens is stained with juice, sweat, hair gel (glue) and cosmetics, please wash it with water and dry it immediately. If not handled in time, the film will fall off.
