The stylish Ambush provides high impact protection to meet and exceed ANSI Z87 + standards…a rare combination. The black, nylon frame wraps around the face providing extra protection while the removable, closed cell foam creates a seal around the eyes. The temples remove and convert to a goggle when you need a little extra assurance your eyewear will stay in place. The shatter-resistant polycarbonate lenses have an anti-fog coating and provide 100% UVA/UVB protection. Great prescription safety glasses!
