We did the same thing with night vision goggles in Vietnam. I had some
folks buy the leather and make the patches. It allowed the guards on the
bunker lines to keep both eyes open while looking through the scope. It was
a big help.

I don't get it, John. You mean the patch would be removed from one
eye and that eye put to the scope? I've never used night vision
goggles, and am having trouble picturing what you've described.

The scope had one eyepiece. The troops would stop looking through it
because they'd keep the other eye shut while looking. Soon both eyes would
tire. By using the patch over one eye, they could use the scope keeping
both eyes open, which was much less a strain on the eyes. Try just closing
one eye for a couple minutes. You'll feel the strain. Now try just covering
the eye with your hand.
