Product Details Frame Men's Large Fit Responsive Fit™ Frame Design – Allows the frame to adjust and flex to the contours of the face. Lens Cylindrical Carbonic-X Lens Fog-X Anti-Fog Inner Lens – A hydrophilic, micro-etched surface that absorbs moisture and disperses 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 anti-fog coatings. TLT (Tapered Lens Technology) – Visual distortion occurs when light waves hit an aggressively-curved lens causing it to bend or distort an object's true size or position. Tapered Lens Technology corrects the distortion by progressively tapering the lens from the optical center towards the outer 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. Carbonic lenses are engineered to be the most impact resistant lens material in the world. Injection molded with Tapered Lens Technology for optical precision and a high level of protection. Ventilation Airflow Lens Technology – Provides active ventilation to reduce fog in even the worst conditions.
