Current take on *authentic* Eagle Pair laser glasses?

[djcmount]

Greetings, all.

I had noted some individuals on here have reservations about EaglePair laser goggles. When I was first getting into lasers many years ago, EaglePair was highly recommended, so I purchased based on that feedback. I purchased directly from Survival Laser. I currently own:
[SL-RLG11] Eagle Pair® 190-400nm & 580-760nm Laser Safety Goggles (I purchased for $41.99 in 2013)
[SL-GLG1] Eagle Pair® 190-540nm & 800-2000nm Laser Safety Goggles ($57.99 in 2012)

The class 4's I currently own:
~1.1W 445nm
~>=3W 445nm
600mW 520nm
680mW 638 nm

Since then, I've noted some individuals had concerns about Eagle Pair laser glasses, but there was also a thread that seemed to suggest that fake EaglePair glasses explained the poor protection https://laserpointerforums.com/threads/question-about-eagle-pair.72792/

I take precautions to avoid any direct or reflected exposure even when wearing eye protection, but I do sometimes burn with them (light hookah coals, etc).

What's everyone's current take on *authentic* Eagle Pair I mentioned above for my collection? The 520nm is a new acquisition and my first green class 4. Should I purchase new glasses, or should these be adequate for burning / pointing indoors at light colored walls? Side note, if someone is being an idiot with a handheld laser at an event (concert / festival /etc), I may put my glasses on as a precaution until security or I can talk to them; this would be the most likely scenario where I might get inadvertent direct exposure - someone else being stupid

If you have a power meter you can test how well your current goggles work: defocus the laser and shine a somewhat broad beam through a pair of goggles and measure what comes through on your power meter. If that transmitted power is <= class 1, your current goggles are fine. Just be sure to wear another pair of goggles or use a cell phone camera to check the meter output. If you don't have a LPM to test with put a white sheet of paper after the goggles and take a picture with your cell phone. There should be no beam or a very weak beam. This isn't as accurate but will give you some idea.

If you're going to be collecting class 4 lasers I'd get a pair of goggles that are certified by companies that don't add a "for personal use only" disclaimer. That puts them more on the hook for the goggles handling the power they say they do. I've bought a lot of good stuff from Survival Laser but eye protection has always been something I've bought from the "big boys".

None of these are particularly inexpensive. But they're your eyes. If you're burning things you're reasonably close to a very bright spot. And don't rule out accidents. Even if you're not "being stupid" you can still make a simple mistake and regret it.
