you ever used NVDs? I think it's difficult to understand for those who haven't tried them out. Even with a good set of NVDs, like the PVS-7 or PVS-14, its still a bit difficult to get oriented, and depth perception -- well good luck with that. I really can't imagine using an $80 pair and expecting anything more than marginally better than just adjusting your eyes to the dark (although admittedly this can take 30 minutes or so) Humans clearly were not made to see in the dark.
