JILERWEAR Professional Laser Safety Glasses for 405nm, 445nm, 450nm, 532nm, 850nm and 190nm-490nm Wavelength Violet/Blue/Red Laser Protection Goggles

Goof fit. They wrap around enough to prevent light from entering from side. Quality build and the case keeps them clean in the shop when not used. I purchased 4 so curious friends can watch the process.

I have been using these for a few months. They are comfortable and provide good side coverage. This is important because I often am looking at several different areas of my engravings, which means that I am sometimes side-to my laser. I have not experienced any eye fatigue and the clarity is quite good. Having a protective case has probably contributed to this because there is safe storage when not in use. I will order more of these in the future if they are still available.

I recently upgraded my 450nm laser engraver to a new 80W head and wanted to make sure my eyes were protected. These glasses do that very well! With a wrap-around design, stray light entering from the side of the glasses is eliminated completely! I can easily and safely get in close to observe and monitor my engraving know that my eyes are safe. I would have given them 5 stars but they unfortunately didn't fit over my reading glasses. I recommend you get a pair and take care of your vision - you only get one set of eyes!!

These safety glasses are so unbelievably effective at blocking the 405nm to 450nm wavelength blue laser light! Every bit of the intensity is filtered leaving just enough light to see the level of focus. I use these with a high powered blue burning laser when burning art onto a big wooden table so these are absolutely necessary and make working with the laser much easier than using dark glasses to decrease some of the intensity. It's important to have a pair luke this with blue laser light use. It doesn't not work well filtering any other spectrum. Green laser light still appears too bright to star at while using these. Get the correct safety glasses for the spectrum you will be working with.

The green blocks out the blue light. If you want to use this for your computer screen, I think it is too strong a green. But for blue LED lights, it is great.

It was a gift for my husband he loves its so much that he wants a new pair in different color.

My wife was extremely happy with her glasses, fit and the way they protect her when she gets her red lights treatments.
