MCWlaser Laser Goggle 190-540 y 800-1700nm Gafas protectoras de seguridad EP-1

5/5 usage. My strongest laser as of yet is an 800 mw sanwu pocket laser, 445 nm. Not a bit of light from my laser will pass through the lense when I shine it through a test pair (bought 3 pairs, waiting to get more). They are fairly comfortable to wear albeit I have a fairly long nose. The only issue I could say is that they aren't the exact product as advertised, as none of my pairs have the gold lettering on them (unless I am seeing things in the displayed images).
Overall you won't be disappointed. Inexpensive and great glasses for O.D+5

They are better than I expected. Very happy so far I have a big head, and these fit PERFECTLY, plus they are super comfortable. For comparison, I have the Pyralex V2G Plus safety goggles, and those were more for a small/medium head; they didn't fit.

The material of these laser goggles is also soft and flexible, which is unexpected. They are not made of semi-hard plastic like the Pyralex goggles, which dig into my face and cut off circulation. Instead, these feel more like a soft rubber; not sure exactly, but they fit to my face rather than sitting on my face.

These goggles/glasses cost a fraction of what an EU/US-made pair of similarly specced option would cost, and although they are one of the most expensive options, given their broad range of spectrum coverage and nice design, they are a no-brainer for most hobbyists I think.

There's a carry case included, and a little spec sheet with instructions. It's nice to have all the OD's listed, but it seems 808nm is actually just OD 4, which is less than the OD5+ these Goggles are advertised as. This is a bit of a problem, as it means these are only rated for 10-watt lasers I think, not 100-watt? Green lasers for example will often leak out a lot of 808-nm light, which is why I went for these goggles over cheaper ones in the first place. Still, adequate for my needs, especially given how much visible light transmission they allow thru, but I'd love to see OD6 or higher instead. No CO2 laser protection either?

I have not actually tested these goggles, but considering the actual brand / model of these goggles seems to be the Eagle Pair EP-1, and that's a seemingly well-respected brand/model with plenty of tests/curves/reviews available online, so I'm not too worried.

The polycarbonate is 2.0-mm thick, which is on par with most safety glasses I guess, though I don't see a Z87+ rating anywhere. The lens is a fingerprint magnet, so thankfully it came with a cleaning cloth. They haven't fogged on me yet, although I suspect you might want to apply some anti-fog to the lens if intending to use these at a protest rally or outside of a well air-conditioned lab.

Plenty bright enough for outdoors and any well-lit room. I'm very happy with the transmission amount given the broad range that it protects against. I bought these for my 450nm laser cutter, but wanted extra protection against green lasers also, all in the form of protective sealed goggles, just in case I ever stumbled into some protest rally. Should keep me safe from most handheld green lasers, i hope, right?
