摘要：
An improved personal protective eyewear device and composition. The device comprises an arc flash faceshield to address issues regarding optical clarity, specifically full color acuity. The compound, which may be used with faceshields and similar PPE, provides a clear grey shield through the use of an infrared dye in that produces a true color lens. Unlike traditional green faceshields, the grey faceshield is a medium-density filter that allows 100% colour acuity. The faceshield is preferably manufactured with polycarbonate material for high-impact and high-mass performance. Most preferably, the faceshield provides protection in the amount of 8.2 cal/cm2 or a category 2 arc hazard exposure protection.
