During the operation of the car, scuffs, scratches and matte areas are formed on the surface of the glasses. The reason for this may be the grains of sandwriters and dirt, the wear of the brushes and so on. These defects violate the transparency of the glass and prevent the driver from concentrating during movement, tire their eyes and, as a result, cause stressful states.It is a mistake to think that all kinds of scratches and points on the windshield can be used to and not notice them.
