For those of us who are getting up in age seeing what you are welding becomes an issue. I tried cheater lenses and they did help but were still lacking. I ended up going to an eye doctor and found that I had a stigmatism (whatever that is) and that was the reason the cheaters were not working to give me the best vison possible while welding. I asked the doctor to give me a set of prescription glasses made for welding. The first prescription glasses I received were not bifocal and while they did a great job close up, I could not see things further out. I asked the doctor to give me some bifocals that would allow for both close and intermediate distance and it worked out great! I'm in my mid 70's, enjoy welding and wanted to share my experience with those who may be approaching their "Golden Years", which are not so golden.
