AG glass is also name anti-reflective glass and anti-glare glass. It is a kind of glass processed specially on its surface . Its characteristic is that the processing change the original glass reflective surface into the surface of matte nonreflective(glass surface irregulrity). The principle is to process the high quality glass double-sided or single-sided, to get a lower refectance comparing with common glass. Its light reflectivity can be reduced from 8% to lower than 1%. The clearer visual effect with the technical processing make viewers experience a better visual senses.
