I bought these because I was tired of the uncomfortable and bulky "fit over your glasses" type of safety glasses. These won't fit over glasses. That's a GOOD thing. It means they're comfortable and will stay on if you don't have to wear glasses underneath. They block 465nm UV and blue great. I'm using them for eye safety around UV cure products and UV inspection, and they're perfect for that.

Good coverage and clear optics. Rating etched into the lens and feel high quality. Blocks the laser as far as I can tell. Much better than typical included glasses

I've been playing with lasers in the 405~550nm range and rated <=4W OD and don't see anything but the reflections. If I change to a lower power that's safe-ish I can clearly see the beam with them off but nothing with them on. Comfortable enough that when I'm "working" and put them to the top of my head while I'm writing some code I've forgot they were there. As I saw someone else noted they do have a bit of a gap bottom and bottom sides, this is true, I don't think the size of my head or cheeks would make a difference. Not a deal breaker for me just be mindful of it.

These really block out the whole spectrum, it's almost difficult to see the laser your're working with. But they really work.
