signac Colore:FRESH BLUE Signac glasses are made ofSignac glasses are made of added polycarbonate. Polycarbonate (PC) is a material with very high mechanical resistance but with limited dynamic resistance. For this reason, our glasses are produced by adding a percentage of ABS to the virgin PC granule, a polymer with elastic fibres that incredibly increases its resistance to torsion and bending. The lenses, also in PC, guarantee original ultraviolet protection and maximum impact resistance. The result
