Night
Vision Goggles are a very unique and resourceful product,
which gives the user of night vision advantages which are not available
in other day optical or night vision devices.
Night
Vision Goggles are electro-optical devices that intensify
(or amplify) existing light instead of relying on a light source of their
own. Image intensifiers capture ambient light and amplify it thousands
of times by electronic means to display the battlefield to a person via
a phosphor display such as Night
Vision Goggles.

A night vision device's range is generally a function of its gain, magnification,
and resolution. As a rule, a powerful lens will give you higher magnification
for viewing far off objects, but it also decreases the amount of light captured.
The optimal combination is a high-speed lens with magnification below 5x. High
gain is required when viewing distant objects, and plays less a role when viewing
objects up close.
Image quality is dependent on the quality of resolution, contrast, and distortion
in images produced by night vision devices. Night vision devices produce a green
monochrome image which is typically sharpest in the center and fuzzier around
the perimeter. Good resolution will give you the ability to distinguish details
of far off objects.
