I have 2.5 diopter cheaters in a AD hood, have headlamp on hood to light work, and sometimes use halogen work light for ambient light source..... Problem being is with my cataract surgery I cannot always see the line I am trying to weld.... The arc flair from the MIG create a light ball around weld line and I lose it... Funny thing is I can almost see good on a 90° joint but really loose it on a flat butt joint... Yes I have tried various ways to help identify line to weld by highlight with white paint stick marker and several other tricks, but overall I still have problem seeing the puddle and keeping it where I want it to go.... Then there was the incident at a TIG welding demonstration, I manages to "ball" the end of the tungsten 3 times and it was a message.... You can't do it.... Old eyes and cataract surgery just don't work as well as they used to...
