There are many different kinds of night vision goggles accessories available today. When you think about night vision goggles and equipments, the first thing that would come in your mind would be an action spy movie. We have seen many movies in which these equipments are used, but most of the time we are confused as to how they work and whether they are used in real life and if so then for what purpose.
It is true that night vision tools are used in real life. If you are equipped with a good quality one, you will be able to see a person standing at a distance of approximately 200-300 feet away from you in complete darkness. Depending on the technology which is implemented, you can use night vision goggles and equipment in two ways.
These two ways are thermal imaging and image enhancement. Now moving on, if you are considering which group of people uses these equipments commonly, the answer is military. Although they are available in many places, stores and shops for public use also, they are commonly used by military. However, the ones used by military are of much superior grade than that is available for public.
These goggles and equipment are fitted with infrared illuminators which allow thermal imaging and image enhancement to take place simultaneously. Many are light weight and allow comfortable viewing experience. These are also available in various generation units which are based on light intensifier tube. These kinds of equipments can be used in hunting, boating, and wildlife observation and in fields of security.
