To measure the quality of a pair of sunglass lenses, in addition to the material, it depends on the refractive index of the lens. The higher the refractive index, the thinner the lens and the higher the price.

Such as the optical characteristics of the lens: sunglasses are flat mirrors, can not have diopter, and should not have optical discriminating methods that affect vision, the simple identification method is to put sunglasses in front of the eyes, through the lens to observe distant targets, such as window frames Or the door frame, etc., then move the glasses up and down, what you are looking at should not have swing and wave deformation.
