The glasses od4 +For myself, I'm not worried about a 5 mw scanner flashing me from time to time even without goggles, I for sure would not stare into it anyway. I wouldn't like it and would try to avoid it as an annoyance. That said, I can't speak for anyone else but myself. With those goggles on, if they had an OD of even as low as 2, no problem.
Level 2 laser can do retinal damage doesn't it?1mW and 5mW are considered eye safe without laser glasses and normally would not harm an eye unless a person deliberately stared into the beam. Laser protective eyewear is normally not necessary, however, even a Class 2 laser can be a distraction, glare or flashblindness hazard for pilots and drivers
Laser glasses for 650nm wavelength OD4+ is more than enough.
See Class 2 info here: https://www.lasersafetyfacts.com/2/
I already bought od4 + goggles that I will have.OD 2 rated laser glasses would reduce that 1-5 mw to 1/100 or .01 to .05 mw, hardly a problem. OD 4 to 1/10,000 of 1-5 mw. But as I wrote earlier, a scanner at that power level is more of an annoyance than a danger to me personally and laser goggles an extreme protection against it.
I don't always put the glasses on when the laser opposite is turned on and blinding.^^^^ This ^^^^ and wondering too??
You work the register at a store??
Wearing laser safety glasses all the time at the register will not let you see just about anything else.
Everything will look blue and dark..
