Never thought of eyesight, I don't believe I'm colour blind, at least I wasn't last time I got checked, however I'm at least 6/7 years overdue for an eye test, oops, got all the kids tested up to date but not got round to doing mine. I did have prescription glasses for close up work but it was only minor, they broke years ago and I haven't struggled without them to much so just not got round to getting a retest. I should really get that done anyway.
I suspect the mask a little bit, but apart from that it seems to be fine and I don't remember having the same problem when using the tig, I can make out the shadows of the corner radius sometimes but not always, I was also wondering if its my lighting in the shed, I have florescent strips down the centre which are behind be when at the bench so I'm working in the shadow. I have got wiring in the walls for dedicated bench task lights but not found any 'on a budget' style yet
I assume the chalk is ok to us, ie doesn't introduce contaminants into the weld? I think that might be my answer
