FreeMascot OD 4+ 190nm-550nm Wavelength Laser Safety Glasses for Typical 405nm, 445nm, 450nm,520nm,532nm Laser Light for Hair Removal Laser Treatment Eye Protection Goggles (Red)

These are great lightweight glasses to use with your laser engraver. that side panel on the eyes is a great little bit of extra protection!

I just received these glasses, on my examination of them, the quality seems excellent.Lenses are totally clear with no visible artifacts anywhere. I tested their stated blocking abilityand both seem to live up to the ratings. I currently have a few lasers so I used my 650nm 100mw redand, my 532nm 75mw green laser for my non-scientific test. On the green laser, the visible output was almost totally blocked which impressed me as that same output without the glasses is extremely bright. Even though 650nm red is out of the stated range, I tried that also and as expected, no blocking was seen so I would not recommend these for red lasers.I will soon receive a 455nm 3,500mw / 3.5W blue laser and will update this review when it arrives next week but at this point, I have no problem recommending these glasses as protection against stray or reflected light when using them for eye protection on lasers.Also, I had no problem seeing through the glasses in low level ambient light and, no problem withthem being uncomfortable to wear. The carrying cases seem fine and should do a good job protecting the glasses during transportation or storage.Just an update, goggles work just as well on my new 455nm - 3500mw laser as they did on the532nm - 75mw green laser.

These are nice and a good buy. Came with a nice case. Bit small for putting over prescription glasses is only reason were not giving a 5 stars.

These are the safest glasses you can get for the price. Test after test proves they block all blue diode laser light.

Works great for high powered lasers! Everything shows up red which is pretty cool. A lot brighter than Eagle Pair, easier to see through.Was very skepital since I only bought Eagle Pair glasses from Lasersafety. This is nothing like those cheap eBay safety glasses, these actually work!Tried 3 of my Sanwu lasers: Green 505-520nm, and 1.6w 445nm, and not a bit of light got through.Definitely worth the money, will buy a couple more of these over Eagle Pair any day!Also very comfortable and easy to wear.

Sharp edges make for an uncomfortable wear.

I have purchased and use many red laser glasses as a professional. Hilti has by far been the highest quality on the market! That being said, this brand is about as high quality but at a fraction of the price! I would absolutely buy again and definitely recommend these to everyone 👌 if you are not happy with this pair, trust that no other will make you happy either.

Works good for 2W and under blue, would not recommend for higher power.

Use these with Sculpfun S9 laser cutter. They seem to work well. They’re the same colour as the integrated shield on the laser head.

Ottimo prodotto funziona benissimo addirittura non riesco a vedere il raggio laser perfetti per la protezione dei occhi li consiglio.

Filters out all of my UV lamp to the point I had to check if it was on

Bought these along with a 5W (output) laser engraver that I fitted to my old 3D printer. It's a blue laser, powerful enough to cut ply/leather/card etc, gotta have the right eye protection (unless you're a former orange US president looking at the eclipse.) and these do the job.
