Factor in the value of superb polarization and three interchangeable lenses on your next outing.

Contoured with swept-back half-frame convenience Smith Factor Polarized Sunglasses are the smart choice for medium faces who start early in the day and stay out past normal bedtimes. This interchangeable design includes four distinct lenses for the varying light conditions encountered while skiing paddling cycling and fly fishing. All lenses have a 9-base Carbonic™ lens structure the most impact-resistant transparent molded material available in the world. The Techlite™ glass lens relies on a special TLT grind process that lightens the Techlite™ lens load while still exceeding ANSI Z80.3 impact resistance and remaining far more scratch resistant than polarized sport eyewear that costs thrice the price. Hydrophilic Megol™ pads along the nose and temples comfortably grip your face even if you're momentarily immersed in water. The Grilamid™ TR90 frames dramatically bend and flex before they break making the Smith Factor Polarized Sunglasses excellent for doing outdoor stuff through a wide range of temperatures.
