Looking at a light through night vision will not blind you. I have been useing night vision for years in my job and have looked at everything from lights pointing at me, to burning vehicles, to explosions (the list goes on). You will not get blinded.
Having said that I will buy this. I have my own set of Gen III PVS-14's, and even if I didn't the ones in this package are just toys, but they are a pretty cool collectors item if you ask me.
