I'm going to have to bite the bullet and get prescription lenses and maybe use a welder's shade green clip-on flip ups on top of those. The bench shield is a great idea but I work pretty close to the torch and I think it'd get in the way (plus I have to wear glasses anyway).
I appreciate the links to Auralens and Phillip's. When it comes time to order I'll probably give Auralens a call but I also like to hear from glassworkers already using the different shades.
Thanks you guys.
