I think we have slightly different goals.
I'd like to find another source for cheap, but "good enough" goggles like the radiant option, but preferably for a bit less, where the guy who comes on the forum and says "Hey I just bought a 1W laser from chinese dropshipper such and such, where can I get cheap goggles." and you KNOW he will not buy expensive ones.
100% agree that testing needs to be done per wavelength, say 405nm, 445nm, 532nm.
What I don't see happening, or being realistic though, is having sellers actually test goggles prior to selling them.
Whenever bluefan is ready, I'd like to get a few of the Uvex goggles out to him, to see if the results are consistent for them.

I suggest we come up with a "good 'nuff" procedure for testing goggles, i.e. nothing completely destructive. Then, it can be up to the sellers to serialize, test, and pass off the data to the end user.
I have some red goggles, they look exactly like the ones that everybody says are great. They let a lot of 445nm through.
I have some yellow goggles. Nobody here seems to use them. They let no 445nm light through.
Bases that need to be covered:
OD rating per wavelength
time for a standard power to completely defeat barrier
When a seller tests goggles, they can etch, carve, or somehow mark that specific pair with an identifying mark and prove that THAT particular pair performed within the community "good 'nuff" specifications.
But yeah, I cringe every time I see someone recommend "Just buy a pair of the red lensed goggles" or something like that.
Oh, and I also suggest we call it something besides "good 'nuff," that was just my example....
Those abex look like they might be worthwhile, they seem like they're specific and non-generic enough to have relatively consistent results across teh board.
