Ah ...... the joys of senior maturity!!!
I have multifocal glasses (no line trifocals plus). Then to top it off, they are auto darkening(need these to see outside) so whatever ultraviolet light gets through, they darken up. Then to make it difficult, I have a different 'scipt and a major and different shaped astigmatism in each eye - all of which means I can't use the Wally World off the shelf specs. I'm resigned to what Uncle Bob has suggested - lots of cut off and grinding wheels and an occasional weld bead that runs wild.
My welding supply laughs at my AARP card and I believe does a 10% ADDER
