The type you are speaking of, Skywalker, is night vision through image intensification.
It is different from FLIR technology. I'm surprised you 'scientific' skeptic types haven't looked it up, or maybe you have and just don't want to reveal the results. Here are
a couple of links for anyone wanting a basic understanding of how both work and a
short cut & paste:
"The essence of these new goggles is “sensor-fusion,” which combines conventional night-vision technology (called image intensification or I2) and thermal sensors (forward-looking infrared).
The I2 wavelength offers a clearer image and can see through glass windows. However, image intensification requires that there be sufficient light to intensify, which makes it ineffective in an Afghan cave. For example, “there was an immediate interest in IR [infrared] on the head when we went to Afghanistan, because of the caves,” said A. Fenner Milton, director of the Army’s Night Vision and Electronic Sensors Directorate.
On the other hand, IR relies on thermal contrast—heat emitted by the target versus the heat emitted by its background—which provides images with better contrast than I2, and can see through obscurants such as dust and smoke. “It requires very little temperature difference between the target and its background for the sensor to detect the target,” said Milton."

This site has a good basic description of both technologies. I will link to the page
starting with how electrons emit different frequency photons because it is necessary
to understand how FLIR works, then go to the 'next page' at the bottom of the article
after reading each page. It is interesting and is geared to the layman.
