The latest TAC method is used in the Excces eyeglass lens - the polarizing filter has been covered with cellulose triacetate. Advanced technologies for producing a multi-layered lens have improved the transparency of the image while providing a low haze value of the lens resulting in the lens not taking moisture. The outer surfaces of the linings are covered with a hard layer highly resistant to abrasion and scratches. TAC lenses provide 100% protection against UV rays and eliminate 99% of light reflections. They provide perfect clarity and full visual comfort. Thanks to the protective layers, these lenses are stable, they do not shrink, they do not become delaminated. Excces glasses have a certificate issued by the London-based Amtre Veritas that provides professional optical protection in accordance with European standards. The frames are made in no nickel technology so that they are antiallergic.
