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.
If your diopter is higher, your lenses are thicker. In this case, the optometrist will generally recommend you a smaller size frame, which can reduce the high diopter and improve the troubles caused by the surrounding deformation and distortion. No matter what your diopter is, under a larger frame, the edge distortion of the lens will be more obvious, and its shape will not match the face properly.
