Recently I get a 50 mw laser and a 5 mw but I was scared about eye damage so. I decided to stick some days with the green a while and search for reflective surface that you should never point I do it the most safety I can. And I get this results
Mirrors (obviously)
Windows (glass). Don't they are like mirrors
Any metal not even cans
Any screen when is turned off
Plastic (transparent) not even PET
Plastified paper (like poker cards)
Some digital clocks have like a green screen don't point at them
They might be more but, for eye safety I stop (they start hurting)
If you know more add them
