Default Search fail - please recommend glasses that protect @532nm+IR?

I'm not having much luck using the search feature, but I keep seeing references in the forums to "everyone's favorite $40 goggles." What $40 goggles would those be? From what I've learned, the common red, under $10 Ebay glasses may protect ok at 532nm, but provide little, if any, IR protection - and 532nm 301 lasers are notorious for excess IR.

Thanks

They are talking about "Eagle Pair" sold by Survival Laser, you can buy them here:

They are more than $40 but there is a 10% discount code LPF445 if it still works.

Thanks! I see that they have the dual protection goggles for <$60.00. My 532nm 301 is nominally a 5mw, but it is probably more than that. It will not burn anything though, so it's output is probably close to 5mw, or not too much higher. Do I really need to worry about IR at that low of a power level?

Not likely you need to worry about it as long as you never get a direct hit to the eye, but the infamous 301 is a gamble, they are cheap Chinese made with no quality control, they can be way over spec or not so be careful.
