The car windshield can interfere with lens discoloration and is therefore less effective when driving. In cold environments, the lens changes slowly. Sometimes the room light is too strong and the lens color is darker and looks very different. The discolored lenses are not dark enough, especially in the strong reflection of the sun, such as beach, snow, water sports, etc., can not replace sunglasses, can not bring enough visual comfort.
