Laser Safety Goggles 532nm OD 6+ Professional 180nm-532nm Wavelength Violet/Blue/Green Protective Glasses for 405nm, 445nm, 450nm, 473nm Wavelengths - Fit Dazzling Lasers, Engraving Machines

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

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.

I really like the look and feel of these safety goggles. They are lightweight, comfortable, and fully envelop the eyes for an assured safe fit. They come with is sturdy woven plastic case to ensure they are well protected. These are overall great goggles that will last for years, and cover the full spectrum (180nm - 532nm) for which I needed them.

I wish it could go over my glasses but its not a deal breaker. They are comfortable.
