Wasn't it the Japanese that tested jamming up troops with loads of Vitamin A, which caused them to see into the NIR range?

Actually, it's pretty odd...SmithsonianMag has a "debunk" of it, and say it was a "misinformation" campaign to send German soldiers on a "wild goose chase". I still might be right about the Japanese doing it, but that article I linked is kinda bizarre in its own right.

But like CrazyRussian said about Farscape, maybe it is about diet...perhaps that is why some people can see "auras", for example...eating something that assists in seeing slightly into the UV range.

Edit: Sorry, didn't notice this post was so old! LOL
