Goggle frames made of this material are soft, pleasant to use, and at the same time extremely resistant to scratches and cracks. DOUBLE GLASS SYSTEM -Double lenses and adequate ventilation are the two basic features that prevent fogging of the goggle lenses. The outer layer is made of hard polycarbonate or polarized glass, and the inner layer is made of cellulose acetate covered with an anti-fog layer. The layer of air between the glass creates a thermal barrier and eliminates fogging. LENS WITH UV 400 FILTER - The UV 400 filter blocks all three ranges of ultraviolet radiation: UVA, UVB and UVC.
