Tungsten Iridium Polarized Lens: Medium to bright light. Cuts harsh glare & sharpens visual acuity. Features a subtle Iridium coating to further reduce glare & tune contrast. The pros of action sports are true originals. They refuse to let the world box them into categories & stamp on a label about who they are or who they should be. That&8217;s the attitude these athletes take to the street & when they find the perfect pair of shades for life beyond competition it&8217;s something authentic that brings original style to a whole new place. We carved clean lines with assertive angles to give them ANTIX a sunglass that balances the fulcrum between street sophistication & outspoken attitude. When original style refuses to follow anyone&8217;s lead this is where it goes.A single continuous lens of pure PLUTONITE strafes the front of this lightweight O MATTER frame & POLARIC ELLIPSOID™ geometry lets us shape it to extend your peripheral view. Thanks to HIGH DEFINITION OPTICS (HDO) visual clarity & impact resistance that meet ANSI Z87.1 standards so it&8217;s ready for whatever life sends your way. A Three-Point Fit holds the lens in precise alignment while offering all-day comfort. UV filtering is an uncompromising 100% & the durable design features sculpturally integrated hinge mechanisms with dual action cams. Multiple lens options are available for these sunglasses. Choose the Warm Grey lens color to reduce glare & maintain color recognition in bright sun or the Black IRIDIUM lens to do the same while precisely balancing light transmission. Our Dark Bronze lens enhances visual contrast with light filtering that begs for blinding solar rays. Two polarized lens options are available & both cut glare with 99% polarization efficiency while eliminating the haze & distortion found with ordinary polarized lenses.
