FREEMASCOT OD 6+ 190nm-490nm Wavelength UV light/Anti Blue Light Blocking Safety Glasses for 405nm, 445nm, 450nm,473nm Laser Light

Comfortable to were, clear vision and no gaps at the sides. These are rated as OD6, which is printed on the lens but no certificate is provided. There is much debate on the forums about whether the lower cost glasses (e.g. <£100) can provide sufficient protection. All I can say is that these look professionally built and I would trust the rating. As a check, I set up a test with a blue led and light meter which does not have the sensitivity to measure down to OD6 (1 millionth transmitted light) but it gave a zero reading on the meter which represented better than 1/50000. This certainly gave me confidence that their rating is correct.

Just right, comfy & pretty stylish. Instantly relieves eye strain as a bonus! Can't see my blue diode laser, so looking good. Really comfy, & lets lots of light through so you're not stepping into your dog's pooh...:-)

Bought to use with my IPL as the light was craaazy bright - they work really well, but my god I don't feel very glamorous when I'm wearing them haha. Still very worth it.

Able to see much better with these rather than the pair supplied with the laser.They also fit over my glasses.

I've been experimenting with a 1.5W class 4 InGaN 450nm blue laser, the safety glasses supplied with it were next to useless so I bought these as a replacement. The quality is good, the frames are quite sturdy and the lenses well made.They block out pretty much all blue light and UV (I have tested this with both 254nm and 365nm sources) but allow green, yellow and red wavelengths to pass. It is possible to see the laser dot (which shows up as yellow on many surfaces, possibly due to fluorescence), but the beam is not easy to see so caution is required. I have no way of testing if the OD really is 6+, however I have been using them with the laser for a couple of days and have no eye problems - with the glasses that came with the laser even looking at the laser dot briefly would leave an imprint on your eye that lasted for several seconds. The laser I am using requires a minimum of OD 3.4, however stronger blue lasers used in engraving and cutting products will require up to OD 6.They come in a good quality case with a neck strap and polishing cloth. Very happy with my purchase.

Love these, they look cool unlike the engraver provided laser glasses.These are much better for blue lasers than the ugly green glasses that come with most diode lasers.Recommend, but I also use at least two light barriers. Either Red laser shroud and or protected enclosure window and or these Safety Glasses. I would never trust a single form of laser protection

Good product A+++++++++++

Difficult to see from the picture but the glasses do have the stated certification written on the lens, which is required by law.Also comes with a case which I didn't spot in the pictures or description which is a nice bonus.They're sturdy and feel like they'll last. As I don't intend to blast a laser into my eye I can't comment on the efficacy of the lenses but all the signs are there.

I bought thre Ortur LM2 a while back and only had done a few smaller projects with it using the supplied green laser glasses. Those are dirt cheap and while they do provide protection I wanted better protection and comfort. These glasses deliver on both! Tried them on when they first arrived and they are a better fit around the nose, and my ears don't get any pinching or pressure from these. They cover a wider range of wavelengths so you get more uniform appearance of light from all sources. This means they worked far better for laser protection, but the added benefits were that my monitor was less distorted and they had a shorter residual color shift effect after you take them off. I've had tinted goggles for winter activites and my green laser glasses and if you wore them for more than 5 minutes, when you take them off everything just looks shifted. Mainly stronger green hues (tinted goggles) or blue (green lenses) for a few minutes after you take them off. Took these off after running a 15 minute burn and had a 30 second yellow-ish tint. Even if they looked ugly, they did a much better job of blocking the light I don't want than expected. I suspect I may have to increase my fire% slightly to see it better whereas the old ones I saw the dot just fine.Tldr: comfy, good coverage, great absorption. If you have a diode laser, get these. You won't regret it.

Exactly as described, fantastic quality!

Bought these safety glasses to use with my blue diode laser etching machine. So here's what you may need to know:1. They fit fairly well over my prescription glasses. This was VERY important to me.2. They are marked on the lens as being OD6+. Without having them tested by a lab, all I can do is hope that they are marked honestly. But I did compare them to the orange material used to block blue light around the bottom of the laser module, itself... and these glasses seem to be just a whisker or two darker. So I'm thinking the OD number is pretty honest.3. The glasses do a pretty good job of sight coverage above, below, and side to side. Could coverage be better? Yes, but that would require them to be the big googles type. For this type of glasses, they are pretty good and more than acceptable.4. The glasses come with croakies (eyeglass retainers) which is GREAT. That will help to be sure that the glasses stay on at all times. The last thing in the world I'd ever want is for them to fall off my face, while working around the laser. The croakies are an excellent addition to the product.5. The included hard zipper case looked pretty decent and will be helpful in protecting the glasses when not in use.6. By the way, they are very orange. So why orange? Well, I'm using a blue diode laser. If you look at the standard color wheel, you will notice that the color blue is opposite of the color orange; so that makes orange the correct color for blue-diode-laser-safety-glasses. Red will also work pretty well, depending on the OD value. but orange is supposedly the best color choice for blue diode laser machines.7. Bottom line: would I purchase again? Yes, I would DEFINITELY purchase them again. I wish that the price was lower, but then again, the price was better than fair. So I should be ashamed of myself for wanting to pay less! LOL... but yes, I would buy them again, if I had to. And they are WAY better than what came with the laser machine.I certainly hope this information was good enough to help you make the right decision on whether to purchase or not. And thank you for reading my review!

Great storage case, distortion free and clear vision. Very prompt delivery and reasonable price.

Great glasses, work perfectly, gave it 4 stars, would have given it 5 but they don't fit over my prescription glasses. I don't have any special big frame glasses. My glasses frame is 1.5" by 2¹/⁸". Overall great glasses would recommend them.
