A perfect complement to the Touchstone, the Smith Optic Backdrop Polarized Sunglasses encompass the same great features like spring hinges and Megol covered contact surfaces. Sharp detailing showcases a medium coverage lens profile that makes it perfect for the leisure activity of your choice.
Polarized Defense - Glare off of reflective surfaces decreases depth perception, reduces visual acuity, and causes eye fatigue. Smith Optics Polarized eyewear uses the highest quality polarized film in the world to filter out 99.9% of this visual static for maximum glare-free comfort. Exactingly pre-shaped in the manufacturing process and precisely aligned in the lenses, Smith polarized film is precisely aligned and pre-shaped in the manufacturing process so that it perfectly matches the curvature of their lenses when installed. Each Smith Optics Polarized lens is in fact two thin wafers of either Techlite glass or Carbonic lens material between which this high-grade polarized film is fitted, protecting it from the elements and ensuring distortion free polarization.
Techlite Lens - Crisp, brilliant optical acuity in an ultra lightweight glass lens. Smith Optics Techlite Glass Polarized lenses deliver the highest level of visual clarity and scratch resistance with distortion-free performance.
Tapered Lens Technology (TLT) - Visual distortion occurs when light waves hit an aggressively-curved lens causing it to bend or distort an objects true size or position. Imagine looking through a fish eye lens. What your eye normally sees, is stretched beyond reality. Get the picture? Tapered Lens Technology corrects the distortion by progressively tapering the lens from the optical center towards the out edges. Light waves are thereby delivered straight to your eye resulting in zero distortion and true optical clarity. What you see is what you get.
Grilamid TR90 Frame - Resilient, tough and flexible. Grilamid is an exceedingly light and durable plastic that will maintain its shape under any temperature changes.
8 Base Lens Curvature - Combining just enough head curve and optical centration to protect you from the elements. The 8 base’s mellowed wrap angle keeps you looking chic. Take ‘em off and you’re on your own.
