Torchwork Safety Glasses - ANSI Z87.1 Certified, Anti-Fog & Scratch Resistant for Welding, Grinding & Metalwork - Perfect for DIY Projects & Professional Workshops

So I bought these for doing some lab glass work on a project at the suggestion of my thesis advisor.They worked great. What I discovered afterwards is that the coating was developed by Sir William Crookes. This special optical coating project was the last project he worked on. For me there is a special connection to these glasses as once again they lend life to the inventor's punning motto, "Ubi Crux Ibi Lux."The one negative to these glasses was that the frame was a little "wonky" as in twisted/not straight. I was able to work them into alignment and didn't have any problems after a bit.I would recommend these glasses to anyone working with open flame as they render the normally invisible portions of the flame visible which helps to prevent accidents.
