I am a full-time RVer who makes torch enameled beads and I have trouble finding places I can work. I heard a rumor about a type of safety glasses which will allow you to see a propane flame in full daylight.
Has anyone heard of these and what are they called?
You may be thinking of Didymium glasses, which are for eating the sodium
flare, UV, etc and make it easier to see the glass under heat.
Maybe soldering goggles ? They have dark tinted glass which allows you to see the flame clearly even in direct sunlight.
I would drop by a welding supply store and ask questions.
They usually have a wide variety of goddles, lenses and such, and you can see what works best.
