If you are working with small hoby lasers and you are running with the cheapie glasses that came with your laser, YOU NEED THESE!. I did not realize how poor a job the frebies did. These are amazing. Your eyesare worth the couple extra bucks to protect them properly. Cheap out on the screws, the wire what ever, DO NOT cheap out on protecting your self! They fit over my glasses with out rubbing the lenz of my glasses. Yes that is a very good thing. Did not realize how bad I needed them.

Not wanting retinal damage, I purchased these glasses for my laser machine. The glasses come in a hard black case the shape of a well filled empanada for giants (I'm hungry) I don't think these glasses protects from all light wavelengths, but it does certainly work for the laser machine I purchased. I'm very happy with the purchase and the price seems to be less than similar eye protection glasses. I was a bit dubious because it was less expensive than other laser protection eyewear, but I'm totally glad I bought these glasses despite my doubts!

These are great. I was so glad to find these! I had purchased one for my dad. I bought these glasses to provide adequate protection for him. These are a good value and give me peace of mind that his eyes will not be damaged while using the device. Thank you!

Have a clearer view and better fit. I feel very confident that my eyes are protected. Even at lower power output levels, it is possible to cause irreversible ocular injury from a single accidental exposure to a direct or reflected laser beam, depending on the wavelength, output and exposure duration. When we wear laser safety glasses, some wavelengths of the spectrum that would normally reach our eyes are filtered out.

These glasses make the laser virtually invisible. You can only see a small dot where it's burning into the material. You don't even see the flashes. I feel very confident that my eyes are protected. Glasses do as they are advertised. Much better than the green that came with my laser. They fit over my prescription glasses fine
