The DIW is OD3 for your 660nm Red laser meaning on a direct shot to the eyes the lenses will attenuate the beam to 0.3mW. The 405nm protection is OD3.5 so for a 100mW Blu Ray the lenses will attenuate the beam to 0.03mW.
The glasses are $98.55 but if you order on the website you can enter the LFP discount code NOR200801 at checkout for a 7.5% discount. You have a choice of nine different styles of frame.
