All products in our Safety Line of Shades are stamped on the left temple of our frames to meet safety glasses marking requirements (set by regulatory government agencies) in the form "Z87+" and also “B + S” - compliant to be worn on industrial job sites like construction. 

The “B” stands for Bomber and the “S” stands for Special Purpose. In addition to these safety glasses lens markings, all of our safety shades meet and exceed the Ansi Z87+ standard. What is ANSI Z87+? It's a requirement for the safety markings we place on our safety line of glasses.
