I don't think it is at all related to welding though. Proper use of welding screen and protective glasses means that in all the time I can only remember having been caught out with flashes a couple of times but as age creeps on I have become a bit long sighted which is perfectly normal.Over 40 everyone will suffer a deterioration of near vision and will need reading glasses, regardless of whether they had 20 20 before that. The exact age this deterioration occurs depends on the individual but it will definitely have occurred by late 40's.
