Night vision goggles

"Thermal night-vision goggles. Hey, here's a question - why doesn't the MALP have a set of these?"

- Captain Samantha Carter and Colonel Jack O'Neill

A night vision device (NVD) is an optical instrument that allows images to be produced in levels of light approaching total darkness. SG-1 and SG-3 used night vision goggles when they travelled to the Land of Light. The Atlantis expedition used night vision goggles when the first travelled to Athos.
