One aspect of night optics you’ll read about relates a device’s built-in technology generation. There are Generation 1, Generation 2, and Generation 3 generation categories assigned to night vision goggles and binoculars. Generation 1 goggles used the most basic and affordable components, whereas Generation 3 is the top of the line. Generation 2 falls somewhere in between, both in overall quality and price. For price-points that relate to general outdoor use, it’s almost a moot point. Generation 2 and 3 technologies are two to three times more expensive than Generation 1, so most general users opt for Generation 1 technology.
