Glasses matching refers to the activity of matching glasses with appropriate glasses.
Glasses are divided into optometry, lens selection, frame selection, polishing and assembly. Optometry is best done in the morning, which is beneficial to the accuracy of optometry. The lens materials are mainly glass and resin.
The materials of the frame are mainly plastic and metal. When matching glasses, it is generally necessary to use a grinder to correct the shape of the lens to match the inner basket of the frame.
