Well I found out the hard way our auto-darkening helmet either is out of time or lens shade is not dark enough for the type of welding I was doing yesterday. Took 12 hours then it hit me. Couldnt open my eyes at all and was fairly high pain on the ole eyeballs. I suffered it out with a cold wash cloth and am 70% today. I was wondering what some of you ole veteran welders would recommend for this type of injury if it would ever happen again??? (I hope it never again) but just in case.
