Polarized sunglasses block glare from light reflecting off flat surfaces, making them very popular among people who spend a lot of time outdoors, driving or particularly near water. Light-sensitive people and those who have had cataract surgery can also benefit from wearing polarized sunglasses.
Plain, simple, and badass, the Dirk looks so tough it broke the mold. Available in polarized and ANSI styles, it features SPY's detail- and mood-boosting HD+ lens and Trident™ polarization. The Dirk is built from virtually indestructible Grilamid® and features snap pin hinges, 8-base polycarbonate ARC® lenses and 100% UV protection.
