Still, it's not like you can't just keep both sets of eyes open; the only animals I know of with IR vision (pit vipers) don't have to close their eyes to use thermal, since they don't see thermal with their eyes anyway. |

VS is normal vision? |

From Basic Set, final paragraph of UV and IRV respectively: You can see both visible light and UV: 10 points. You can switch freely between normal vision and Infravision: 10 points. |

I'd say it's a +0% switch to have it either work as written (switch freely) or work like UV (VS + IR all the time). After all, you can theoretically just declare you're switching back and forth all the time. The benefit of having it on all the time - seeing clearly via the VS which also gives you colours, and being able to detect heat sources (or the suspicious lack of heat, as in creatures with no body heat trying to pass as normal) all at once - seems like it balances out with the possibility of being temporary blinded by a sudden intense burst of IR light that people without IRV might only perceive as warmth.

Regarding colours: AFAIK, IRV has colours too - objects don't emit/reflect IR radiation uniformly across the spectrum; different do more or less in various sections of the spectrum, just like various objects reflect VS light non-uniformly. Okay, not 'just like', but you get the idea. |

In fact, I've always wondered why (as far as I know) IR images only use the (presumably) single IR channel and don't even bother using VS-range channels (cheap to image) with tone mapping to provide more detail under all conditions. |

Which is grossly overpriced, but the advantage probably also does too much. Ponder how to more appropriately redo senses. Some thoughts:

Re: Reality check: Dark Vision and Hyperspectral Vision
Possibly because false-colour imaging tricks human visual systems into doing stupid stuff, and human brains into doing stupid stuff. You can overcome it when you're sitting at a desk analyzing telescope data or satellite imagery, but when you're in a combat situation (which IIRC most of this tech was initially developed for) you don't want to have random eye-brain interface farts.
Well, that and 3 different sensors costs more than 3x one sensor, makes the assembly bigger, gives it more parts to fail, and makes the software more complicated which means more expensive and more likely to have bugs. Which might be a bigger factor, even with civilians without life-or-death situations on the line.
