One place that's easy to get "Welders Eye" is in the coalmines, and you don't even have to be welding.... I have done a lot of welding underground and that was before they came out with 'Auto-Darkening Helmets', but one wouldn't have helped much because it was dark anyway.. You had to do a lot of 'head flipping' and you couldn't wear a light & a welding helmet.
The welding arc would reflect off the coal & the roof of the mines..especially if the roof was wet, and it being dark made it easy to get your eyes burned.
I got so use to 'head flipping' that it turned into a habit... and my wife would remind me in a store that i wasn't in the mines.
