The Uvex Genesis Glasses, 9-base wraparound uni-lens style offers maximum protective coverage and superior peripheral vision; soft, elastomer browguard diffuses impact while providing comfort at all key points. The Uvextreme anti-fog lens coating combines with a ventilation channel to minimize fog and moisture. It also provides better scratch resistance than many competitive anti-fog coated products. A soft, flexible browguard plus adjustable temples and nose piece provide maximum comfort and customization. Engineered for maximum comfort and protection, ideal for use at the range or as hunting glasses. Visible light transmittance at about 15 percent with the Espresso lens. It differs from a standard gray lens in that the tint tends to make colors pop, though not as much as vermillion. Overall, espresso gives a shooter better color recognition and contrast in sunshine or other bright light, as opposed to simply darkening the scene like most gray lenses do. For these reasons, espresso lenses can be a great option for wing shooting or range work on bright, sunny days. All Howard Leight Uvex safety eyewear and earmuffs are compatible for use with each other. Meets ANSI Z87.1-2015 (High Impact) and CSA Z94.3 standard. Meets Military V0 ballistic test for impact.
