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.

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.

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

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.
