These days, there are a wide range of night vision goggles available on the market. Apart from goggles, there are also other kinds of equipments available that can be used to view in complete darkness. Thermal night vision cameras and binoculars are some examples of these equipments.
Although there are different types of equipments available, they generally operate in two ways which are thermal imaging and image enhancement. The latest versions of NV goggles make use of both the technology and therefore enable effective viewing. They enable viewers to see with perception and clarity. When you use a standard NV goggle, you will even be able to see a person in the dark that is standing about 200-250 feet away from you.
Previously these types of equipments were only used by the military. Today, they are used by various groups including hikers, campers and fishermen. Furthermore, the cheap night vision goggles are used as toys by many kids as well. Although the ones available for public use are not as effective as the ones which are used by the military personnel, they can provide a very unique kind of experience.
These special kinds of goggles are usually characterized by the different generations. Starting from Gen 1, now we have up to Gen 4 which means that the higher the Gen number, the more advanced the NV goggles. The latest versions make use of both the technology and enables viewers to locate images even in complete darkness.
