What brands of face shields are preffered? Wondering about lightness comfort. Shade 5 o 3?

see this thread for my response

If all you ware using is silver, some people just use clear glasses. After looking at the issue for some time, it appears that if you never weld, you can get away with a #2 for brass.

really dark glasses suffice , there round lens ones that screw together around the glass disc.
