Different Generations of Night Vision Goggles
Night Vision Goggles are categorized on the basis of performance and clarity. The goggles used by a civilian will never be used by a cop, a military person and so on. Depending upon the functions and nature of job there are different types of goggles. Normally, civilians go for the first generation goggles and they are the most common ones that you get to buy at a store, both online and street. The available light will be magnified a thousand times so you can see all the normal things. However there will be a little bit of blur at the edges. The second generation goggles are used by law enforcement officials because they need more quality to get their job done. Other professionals also use these second generation goggles. Third generation goggles are used by military people because they need impeccable quality when they go out on a mission. They cannot afford to have any blurry images because it will affect their quality of work.
