My work with safety eye-wear lead to my involvement with glass blowers and welders. Watching and understanding how these lenses neutralize sodium flare to not only protect but also to comfort the eyes.
I have produced a multi-functioning eye-wear solution at a reasonable cost. Let me introduce you to my PX adaptable didymium glasses. We have four sizes 50-56 in gold or gunmetal. A glass didymium clip fits perfectly over the frame and meets all safety standards. Please call for pricing.
