Trouble with cheaters is that they add an extra lens element that can fog up . . . usually UNDER the cheater, so you have to get it out to wipe it off, after which it might fog up again. Repeatedly. Glasses fog too, but they're quicker to wipe off.
If I drive somewhere to weld, when I've parked I will sometimes raise the hood of the vehicle and place my helmet and gas-goggles in a warm place above the engine. If you have everything warm, it won't fog. Of course, it's better not to overcook the fancy electronics . . .
"shovelon," regarding your "welder" and "weldor," I once put the latter on an employment application and got chewed out for not correcting my spelling. I rather enjoyed correcting the HR person (but of course didn't get the job). Later I decided that while "weldor" might be correct, insisting on it is pedantic, and I never use it anymore.
But I can still be pedantic, LOL: 1) Willie, the problem with old eyes isn't so much the muscles as the lens they act upon, which starts life very soft and flexible but in old age has become like a rubber pea you could bounce on the table. 2) JD1, photographers will tell you Japan makes some of the world's best optics. Don't confuse the Japanese, who are perfectionists and want to be proud of their company and their products, with the Chinese, who prefer to make a lot of money with minimal overhead and trouble. Of course, if the Chinese discover they can make more money with better quality, they will accept that and go with it. What else do y'all wanta know?
