A monocular is a NIGHT VISION product that has one eyepiece and one objective. It usually refers to a unit that is held in the hands and is typically between 2x and 5x. An NV monocular has many advantages. It is the smallest NV unit, as well as the least expensive and it offers as much performance as a binocular or goggle. The only disadvantage of a night vision monocular is that it allows you to use only one eye when you observe. Over long observing sessions, this can create eye strain and fatigue, but, fortunately, most NV observing is intermittent, not continuous.

A NIGHT VISION binocular is much the same as a daylight binocular in that it offers two eyepieces and two front lenses with the addition, of course, of a NIGHT VISION intensifier tube. a NIGHT VISION binocular still only uses one intensifier tube system, so it won't offer greater performance or range than a monocular, but it will provide more comfortable viewing since you are you using both eyes. However, a NIGHT VISION binocular will also be heavier and more expensive than a NIGHT VISION monocular.

Goggle
A NIGHT VISION goggle is any unit that comes with a headset. It comes in three versions:
Monocular goggle
Bi-ocular goggle
Binocular goggle
As the name suggests, this goggle uses a monocular mounted to a headset. This is the lightest and least expensive type of night vision goggle (night vision system), but since you are using only one eye and one optical system, it will not be as comfortable to use as a system with two eyepieces, not will it provide any depth perception.
The bi-ocular goggle feature two eyepieces, but only one front lens. This improves viewing comfort over a monocular goggle, but because there is only one front lens, there is no improvement in depth perception over a monocular.
The binocular goggle uses two eyepieces and two front lenses. This not only provides better viewing comfort than a monocular, it also provides depth perception since it is using two different optical systems. This is a important feature if you are using a goggle while in motion, say walking or even driving off road.
