The maintenance principle of resin prescription glasses lenses is to keep them bright and clean, free from oil stains, and avoid scratches. Before wiping the lens, it is best to rinse it with tap water or use neutral fat or a special cleaning agent to clean it. After washing it with water, use a special mirror cloth to wipe it clean. Clean the fine seams between the glasses frames and gently brush with a soft old toothbrush to remove dirt.
In daily life, lenses should be avoided from contacting high temperatures as much as possible, because the film will be damaged or even fall off due to the inconsistency of thermal expansion between the film and the lens substrate under high temperatures. When using, lenses should also be avoided from contacting strong organic solvents, such as acetone, ether, and perfume
Because these organic solvents can affect the surface smoothness of the lenses, it is also important to develop a fixed habit of placing glasses. First, wrap the lenses with a flannel cloth, and then fold the lens legs. To prevent heavy pressure on the glasses, they can be placed in a hard glasses storage box.
Remember to never dry wipe the lens. Be sure to rinse both sides of the lens with water first and then use a special mirror cloth to wipe it. If you have free time, you can also use an ultrasonic cleaning machine to clean the lenses at the eyewear store. Generally, it is free, and whether you have matched glasses at that store or not, you can clean them for free.
