Reach maximum visual performance and keep your eyes protected with the Wiley X Knife. These glasses meet ANSI standards for high velocity impact safety and are made with shatterproof Selenite polycarbonate lenses for long-lasting durability and unmatched protection. The removable Facial Cavity seal, a staple of Wiley X's Climate Control series, keeps out debris, wind and peripheral light while using multi-layer foam for a comfortable fit. The lenses are treated with a T-Shell lens coating to resist scratching, providing constant visual clarity in harsh environments. Using a Top Down ventilation design to eliminate fogging, these glasses deliver sharp vision and optimal eye protection in any setting.

• Lenses block out 100% of all UVA and UVB rays up to 400 nm
• Triloid nylon frames are virtually indestructible
• Lenses made of shatterproof Selenite polycarbonate
• Top Down ventilation design eliminates fog
• Coated with T-Shell lens coating to reduce scratching
• Detachable Facial Cavity Seal uses multi-layer foam to provide comfort and keep out debris, wind and even peripheral light
• Polarized models feature Filter 8 lenses, which combine eight layers of technology for 100% polarization
• Filter 8 lenses feature two Selenite polycarbonate lenses, two slick hydrophobic coatings, two T-Shell scratch-resistant layers, one Violet 4 anti-reflective coating and one Filter 8 polarized film layer (polarized lenses only)
• Clear lenses offer complete light transmission, ideal for use at dusk/dawn or in overcast conditions. Light transmission: 89%
• Smoke Gray lenses greatly reduce glare and won't distort colors, good for bright lighting situations. Light transmission: 14%-20% (depending on frame style)
• Polarized Bronze lenses improve contrast and enhance ground level contours in most lighting conditions. Light transmission: 18%
• Polarized Silver Flash (Smoke Gray) lenses use a multi-coat, Z-Oxide mirror over smoke lenses. Efficiently reduces glare on bright days. Light transmission: 13%
• Polarized Emerald Mirror (Amber) lenses are designed specifically for improved visual definition and enhanced color contrast. Amber tinted lenses under an emerald green multi-coat mirror surface. Superior visual clarity and distinct colors in any lighting condition. Light transmission: 18%
• Transmission percentage describes the amount/rate of light that actually passes through the lenses into the eyes
• Prescription lens compatible
