&gt; The next step, more controversial, would be super-vision of tetrachromacity, perhaps infra-red and ultra-violet sensitivity. Night vision glasses no longer needed for enhanced soldiers.<p>Utter poppycock.<p>The cornea and lens in humans are UV opaque, which is a very good thing because UV light is damaging. People without a lens (aphakia) are reported to perceive UV light, but this is otherwise an undesirable condition. As to infrared, some people can already see up to around 750nm or so (NIR) with awful quantum efficiency. Pit vipers and some fish have limited perception of IR, but I&#x27;m not aware of any animals that can see IR in the conventional sense… being warm blooded presents a real problem, for one.<p>Plainly, there are limits to what can be achieved in hyperspectral imaging due to materials, and that&#x27;s without the constraints of biology thrown in the mix.
