Night vision, a interesting question

The meaning of "night binoculars" in WWII is just a ordinary binocular with a large lins for incoming light. (sorry now for my english, cos it's not my native language). It just works so that a i.e. 7x50 binocular can in bad lightning make it look brighter in the binoculars. So in some cases this kind of binoculars could make the night look brighter. It will noit work with a 6x35 binoculars. This will just make it even worse.
This is not to compare with later developed night vision devices as goggles or so. Thats another technique.
