The AN/PSQ-42 Enhanced Night Vision Goggle-Binocular (ENVG-B) is a third-generation passive binocular night vision device developed for the United States Army by L3Harris. It combines dual tube image-intensifying (I²) and thermal-imaging technologies into a single goggle, enabling vision in low-light conditions.
The AN/PSQ-20 Enhanced Night Vision Goggle (ENVG) is a third-generation passive monocular night vision device developed for the United States Armed Forces by ITT Exelis. It fuses image-intensifying and thermal-imaging technologies, enabling vision in conditions with very little light. The two methods can be used simultaneously or individually.
The AN/PVS-7 is a single tube biocular night vision device. Third-generation image intensifiers are able to be installed and are standard for military night vision. Most newer PVS-7 intensifier tubes are auto-gated to prevent image intensifier damage if exposed to intense light. The goggles have a built-in infrared Illuminator for low-light ...
A US airman tests AN/AVS-10 panoramic night-vision goggles in March 2006. Member of the U.S. Marine Corps testing out the GPNVG-18. Night vision devices typically have a limited field of view (FoV); the commonly used AN/PVS-14 has a FoV of 40, [66] less than the 95° monocular horizontal FoV and humans' 190° binocular horizontal FoV.

A specific type of NVD, the night vision goggle (NVG) is a night vision device with dual eyepieces. The device can utilize either one intensifier tube with the same image sent to both eyes, or a separate image intensifier tube for each eye. Night vision goggles combined with magnification lenses constitutes night vision binoculars.
This is particularly important for people who are 55 and older who deal with more eye strain as vision changes and focusing close up becomes more challenging, Hilal-Campo explains.
