yep, caught a case or arc-eye once from accidentally striking arc while
I was moving to get in better position ... hurts like hell.

Just from ONE arc for a few seconds? That can't be true. I've often
watched people welding for a couple of minutes.

There is a vast difference from watching someone weld from a few feet
away, to staring directly into the weld pool from close range.

I'd say I was only twice the distance.

So at welding distance you'll get four times the exposure.
