Review on 200Nm 2000Nm Treatment Cosmetology Operator Protection by Tanner Miller

Revainrating 1 out of 5

Not safe for laser engraving.

The very first problem I noticed was that I can see blue through these glasses. shifted to grey. Immediate retinal burn from accidentally viewing a 7W 450nm beam (2.5W actual optical power). I don't think these are anything other than sunglasses as the claimed spectrum coverage is too wide. My fault is that I wasn't paying attention.
