No problem. I was a welder for 10 years or so professionaly, then I had a lung collapse, and the Dr. told me if I kept welding and smoking, I would be dead in 5 years. I quit both for the most part. I still weld enough to keep my cert current, but I quit smoking completely. I may allow my cert to laps though...It just isn't worth it to keep anymore for something I hardly use.

Once you get one of those lens', you will notice a HUGE difference. and your welds will show it too. I switched 1/2 way through tech school, and graduated 2nd in my class. Only 2nd and not 1st because I wouldn't smoke pot w/ the instructor. LOL
