Tri Acetate Cellulose (TAC) polarized lenses feature a new lens technology
formulated for superior visual and polarization clarity.
They have a scratch coating and block 100% harmful UV rays up to 400 nanometers.
These lenses are very lightweight and highly impact resistant.
Tac Glasses block harmful UV rays and glare,
improving visibility against reflective surfaces like asphalt covered roads, snow, and sand.
