Just received my NBY3-II-B 450nm Blue laser, suppose to be 1 watt, it uses 2x 18650 cells. I did not buy glasses and can tell from turning it on for a few seconds that should be my next purchase. So I only have the blue laser and looking for reasonable pair of glasses for this color-450nm or wavelength, I will have to order one from the internet so while I and waiting is there anything I can use like, welding helmet, real dark sunglasses or camera lens filters, while I am waiting?
