Lenses are injection molded from thick 1.9mm shatter-resistant polycarbonate that is built to withstand Z87 Mass Impact Standards.
Each pair of USA made Vise® is boldly marked Z87 on the frame, arm and lens.
The USA Vise builds upon the Vise® legacy with a lightweight Grilamid TR90 premium thermoplastic frame that is uncoated and polished, offering a high luster gloss finish. The uncoated nature of the frame enhances resistance to chemicals, while the TR90 material is overall more durable and flexible.
Two traditional high-quality 5-barrel hinges in gold plating securely hold the entire assembly together, contributing to the overall premium fit and finish.
