These googles shift or compress a section of the spectrum to allow human vision to see other parts of the spectrum. For example, double the frequency, or compress a wide bandwidth down into the narrow band of visible light.

       Baked, surely? - isn't this what Infra-Red night vision goggles are?

       They are a specific limited implementation of this general idea.

       // isn't this what Infra-Red night vision goggles are? //   

       No, they're not. Not even a "limited implementation".   

       Typically, IR or image intensifier devices take a broad spectrum of photons and amplify them and convert them to a monochromatic image. There's no "colour".   

       There are telescope optics that can upshift the IR waveband to the optical one, producing "false colour" images, but there's no specific wearable device that does this. Yet.   

       They are under development, so that "Infra-Red Colours" can be seen - it would allow much more subtle discrimination, for example detecting camouflaged or otherwise concealed personnel and vehicles. However, they're certainly not WKTE.   

       [+] for a consumer-grade version.   

       Combined with headphones incorporating an audio downshifter, they could be used for watching bats.

       8th didn’t mention it, so I will - in Star Trek: The Next Generation, this functionality was built into Geordi’s visor. So I guess this idea would have to be filed under WTCTTISITMWIBNIIWR.   

       And in real life, it’s getting closer. I have a colleague who has been losing his vision over the past few years, and is taking it in good spirits. He has used many such visors - with gleeful excitement for trying out new toys - providing magnification and other vision enhancements. Some of them can increase and decrease color saturation of whatever he’s looking at, and do some false colouring for highlights. But actual compression, and bringing IR and UV into visible range is not on their menu (yet).   

       I’ve linked a patent for the kind of iR false-color goggles similar to what 8th mentioned. From the patent wording: "Wording from the linked patent document: "The goggles are useful for looking at vegetation to identify different species and for determining the health of the vegetation, and to detect some forms of camouflage." They use a bit of filter trickery though, not true frequency compression.

       No, the ones we're describing are fully active units. They have an IR-sensitive CCD which can detect multiple wavelengths, and do the false-colour interpretation electronically to a stereoscopic LCD display - like an Oculus, or Google Cardboard. No filters involved, other than the visible-blocking filter on the objective lenses.

       8th, you were responding to my original short note while I was still editing/expanding it. To do it properly will indeed require active electronics, like a VR headset or my colleague’s visors.
