The US military is the leading equipped force in the world. Most military units use the most modern equipment to maximize the soldiers' activities, including night vision goggles.
Operation conditions in the dark night environment are always a great obstacle for every soldier, poor visibility or even 0, making it difficult to move and observe the enemy. Therefore, night vision goggles have created an advantage for the US military in every night of fighting or in less light areas.

The night vision equipment of the US military has two types of night vision equipment (NVD) and thermal imaging observation device . NVD devices are built on a combination of two spectral and intensity range methods to help people observe the surroundings in low light conditions.
The structure of the NVD includes: 1 or 2 lenses that amplify the image with the same image sent to 2 eyes or a separate lens for each eye in a hard plastic case. The human eye has a much poorer night vision than other animals due to the lack of "Tapetum lucidum" , a tissue in the eyes of many vertebrate animals. It is located behind the retina that is able to reflect light back through the retina thereby increasing the intensity of light to the photoreceptors to help see better in low light conditions.

In addition, NVD can be combined with a magnifying lens to create night vision binoculars.
The night vision equipment of the US military has four generations, each of which has unique characteristics over its predecessor, allowing people to observe even tiny objects in the dark night.
In addition to military applications, NVD is also used for civil purposes in studying animal activities at night.
