There are many different variables that affect the distance that one can see with a night vision device, among them the object's size, the level of details being sought from the object and the conditions of observation. Night vision devices detect much further under a full moon and clear skies than they will under a new moon and cloudy skies.
Many different formulas are used to determine the statistic of maximum viewing range and the method of calculation varies by manufacturer.
The important factors to consider when evaluating any night vision device are the intensifier tube's generation, s/n ratio, level of magnification, specified resolution, along with the clarity & light transmission efficiency of the optical system.
All night vision devices sold by B&H have mechanisms in place to protect the intensifier tube from a sudden burst of bright light, but this does not mean that bright light doesn't damage the device. No matter what, bright light in any form is not good for the longevity and performance of image intensifier tubes.
