I usually braze with OA - Maybe that's why? The OP is just using safety glasses, so maybe the flare from MAPP brazing isn't as bright.
I've used
#3 lens with oxy/ace and oxy/pro (I've also not and it's definitely harder), but you're correct in surmising the oxy/fuel operation is a LOT brighter. Curt Goodrich, who used to do frames for Rivendell, told me that the occasional user wouldn't risk eye damage, but it was essential for the professional who does it every day. The flux doesn't light up so much with mapp so you can see the puddle and the flux pretty well.
Alex Wetmore likes a didymium lens - says he can read the color temperature of the metal better - but those are expensive. Then there's those old pictures of Ernest Csuka, of Alex Singer, brazing in nothing but a sweater and slacks, and he built amazing frames without going blind. To each his own, that's what I say.
