Having worn only one of those things on, the depth perception and range of view ******* sucks. Now when you have two on like the guy in the picture presents, you can take in so much more from the picture you are seeing.
For example, form your hands into small binoculars and try to look through them. You will notice you can't see much other than directly forward. Now open those hands considerably, you can now see much more and be more aware of your surroundings.
The military is now dabbling or has been dabbling in 8 lens NVGs/Thermal goggles.
Bigger field of view. So instead of just being able to see forward in the night you can see more off to your side and it helps situation awareness a lot.
Now, we Marines get all the hand-me-down gear from you assholes, as such we're often still operating with monocular NVGs. So I may be wrong but I'm pretty sure this jackass just managed to rig two sets of NVGs to his face.
Its a pair of wide-view Night Vision Goggles, a real thing. Basically its so they have a better field of view, cos normally with NVGs its like looking thru binoculars.
