Cylindrical Carbonic-X Lens - Smith has set the standard in lens performance. Each lens is individually molded to offer optimum scratch and impact resistance, increased visual acuity, and enhanced contrast sensitivity. The inner lens is impregnated with Smith's Anti-Fog lens treatments for increased anti-fog performance. The Carbonic-X lens meets Class 1 optical standards as well as ANSI Z80.3 standards.
100% UVA/B/C Protection - All Smith lenses provide 100% protection from harmful UVA/B/C rays.
ChromaPop - ChromaPop lenses are the most advanced polarized lenses in the world and allow you to see true colors more quickly to maximize your visual experience. By blocking color wave intersections as they pass through the lens, ChromaPop is able to eliminate color confusion, enabling you to see the outside world with an unparalleled level of vibrancy beyond normal capabilities.
*Available only on select colors.
Fog-X Lens Treatment - Smith's Fog-X treatment employs a hydrophilic, micro-etched surface to absorb moisture and disperse it over a wide surface area to prevent fogging. Because it is physically carved into the lens, it can't be wiped away like other fog treatments.
Tapered Lens Technology (TLT) - When light passes through a medium it refracts, or changes course. If left uncorrected this refraction can cause visual distortion and eye fatigue. Smith's Tapered Lens Technology straightens out the incoming light rays by progressively tapering the lens from the optical center toward the peripheral view. What this means for you is that you see with 100% accuracy and maximum comfort.
VLT stands for Variable Light Transmittance, which is the percentage of light that is allowed to penetrate the lens, for brighter conditions you'll want a lower VLT rating and with darker conditions you'll want a higher VLT rating.
Stormy/Night - VLT between 55% and 100%
