FreeMascot Professional OD 6+ 190nm-490nm Wavelength Violet/Blue Laser Safety Glasses for 405nm, 445nm, 450nm,473nm Laser

Blue light from electronics was keeping me from sleeping well. I’d wake often and have trouble getting back to sleep. I had tried orange glasses before but they often broke. I got tired of replacing them and eventually forgot about them.When I went looking for a good pair of cheap, orange glasses, I bought and returned several of them for having the same problems as the old ones. Then I found this product.These glasses are sturdy, fit over the large lenses of my regular glasses, allowing me to use the iPhone or iPad to read before going to bed. They also work for tv watching tv in the evenings. I start wearing them for these things about 7 pm and have been sleeping much better.While they are not cheap, I’m very happy to have something that works. I’m also glad to stop searching for something that works. I find they are well worth the cost. I even bought a pair for a family member who wears the el cheapo brand. Once I tried them, I knew anyone else who wears these things would be happy, too.

I bought this to pair with my 20W diode laser, and I'm very happy with them so far. no distortion to speak of and they don't make everything too dim. everything just has a yellow tint. And they fit nicely over my relatively large glasses. Glad I bought these - they fit better than the glasses that came with my laser, and I have more trust that they are doing a good job protecting my eyes.

good UV glass

They seem to work well at stopping the blue light of my laser, so that is a good thing.The best part is that they fit over the glasses, which I need to be able to see. And they are comfortable while doing so.

Comfortably fits over glasses, adequate side protection. Good value for laser glasses. Certainly worth paying a little more to protect your eyes. This color allows you to still see your work and computer unlike cheaper dark green and red glasses.

Exactly as advertised. Protects eyes very well.

I like these a lot more than the ones that come with my laser. They let in more of the safe light so you can see what is happening better. I can fit these over my glasses, but it is not very comfortable and I don't do it.

These will blow all the cheap glasses that come with laser engravers out of the water.No comparison to the ones we received with engraver. Protect your eyes, if these cover what you need you won't be sorry you purchased.

I bought a new 10W Atomstack diode laser. It came with the usual cheap pair of glasses. Those are dark, you can't see anything else.These are just as good at cutting out the laser light, but you can still see other things in the room. They also fit over my son's glasses perfectly.So they are a great investment, he wears them at all times when the laser is on.

After using the glasses provided with my Laser CNC using these glasses was literally a night to day experience. I am super impressed by the improved clarity and comfort

Exactly as described. Very good quality and much easier to see through than the less expensive ones and still get the protection you need.

You know these work when you look out a window and can instantly see clarity and higher detail in everything. Same with looking at a computer screen, what a difference. I bought these to use with a blue neatcell and found there is plenty of protection on the sides with the extra wrap around design.I now also reach for these when using the computer for long periods of time. They're really comfortable. They fit over prescription glasses well and has significantly reduced eye strain. You do have to adjust the arms of the glasses if your head is narrower like mine, but once you do, they don't slip down when looking down. I did notice that with longer wear, they leave frame marks on my face. The wavelength protection is etched at the top of the lenses. Proper safety specs information is not included with the glasses, so 1 star off.
