Microsoft is also developing something similar based on HoloLens glasses and even successfully selling it to the Pentagon. I hope that all this will eventually appear in consumer products. Looks tempting, and can come in handy in many cases.

Specialists associate the further development of night vision technology with the following main directions: increasing the range of action to values corresponding to the visibility range during the day.
