Night-vision lenses so thin and light that we can all see in the dark
From evening drives to navigating a house or a park in the dark, there are so many situations where it'd be handy to slip on a simple pair of night-vision lenses and the world that's beyond human optical perception could be illuminated like never before. This vision could be a reality, with a…

This isn't really night vision in the typical sense. It's an Infrared camera in a thin package.
Also Military night vision is described wrong. The photon doubled is quite small. The problem is that afterwards the image needs to be turned again. That is done with fiberoptics. Those take the amount of space.
“This is the first demonstration of high resolution up-conversion imaging from 1550-nm infrared to visible 550-nm light in a non-local metasurface," said author Rocio Camacho Morales. "We choose these wavelengths because 1,550 nm, an infrared light, is commonly used for telecommunications, and 550 nm is visible light to which human eyes are highly sensitive. Future research will include expanding the range of wavelengths the device is sensitive to, aiming to obtain broadband IR imaging, as well as exploring image processing, including edge detection.”
That does not sound like an Infrared camera.
You're right, there is no capture or recording of light in this system. Electromagnetic metasurfaces directly alter the waveform of photons as they pass through. In this instance it directly converts infrared light into visible 550nm (green) light.
It doesn't immediately sound like it, but having read all that it does sound like it's what it is even if they dressed it up a bunch. What parts make you think differently?
Surly there is a lenses that flips images upside down. Have we tried just training people to deal with upside down surly it doesnt take too long for the brain to adapt.
It doesn't. I recall an experiment a few decades ago where they turned the world upside down. Didn't take participants long to "normalise" the image.
When they removed the experiment, took even shorter to flip back.
I seem to recall it being done in a train carriage, as art, but I'm not sure.
Huh guess a bit more training and u can totally remove the fibre optic flipping which if i recall correctly is the most expensive part.
The soldiers just have to wear the goggles all the time, or they'll see upside down for several minutes.
Surly u can adapt to the change given enough practice.
The device captures visible and infrared light, just like a typical night vision scope. They're working on expanding the spectrum too, which could lead to some interesting and useful results. I understand that, for instance, skin cancers are more visible under certain UV wavelengths, so imagine a doctor being able to just put on a pair of glasses that convert that wavelength to give you a once over during a checkup.
