Readability/write-ability with nightvision goggles/devices?
Can someone tell me how the read and write-ability is with night vision goggles? are there any difficulties and if so in which cases is it hard to read or write?
photos would be very welcome!

Things like signs that are made to contrast and be easily read during normal conditions can be read with NOD's, but because most NOD's can only be focused for so close (5-10m?) you won't be able to read anything in front of your face.
It can be done.....I've done it just to try it with an NVE that could focus quite close...but as already stated, red light and some cover is probably simplest/easiest.
Even map reading is possible. One problem is that some colors that are high contrast in daylight are not that through NVD's. And vice-versa. NVD's see different wave-lengths compared to naked eye. For instance, I have black boots that look white through NVD's.
You loose depth perception with the PVS-14 and other Monocular type NVGs (nothing like watching soldiers running into trees at night).
So you don't use NVGs to read/write?
Nope....but tried it to ensure I understood the kit I was issued.....red light works easier....and another good point made about colour contrast for both using NVE as well as red light...some work better than others.Originally Posted by OMON
it makes it easier if you break in infrared chem light. but the focus adjustment is the issue...it is hard to read close ...depth perception...
Reading signs etc. is fine. But depth perception is effected so it can be difficult to read small writing up close.
So as long asthe map or paper is illuminated you can read/write?
As long as you have good map that is readable it is possible to read it. I have read a book with NVD's just for the heck of it. In normal night conditions (starlight, not too cloudy) it is perfectly doable without illumination. Any moonlight makes it very easy.
It is just easier to do with red light because the focusing at close range is very finicky and the field of view is smaller with NVD's.
Just curious, why are you asking this and why would you want to be able to read or write under NODs? I personally always had my NODs adjusted for far. It was kind of claustrophobic when exfiling, infiling, or getting in a stack. That's the main issue. NODs are sharp enough these days to be able to read fine print as long as there is enough light, so the gain isn't cranked up like crazy causing a ton of noise.
I always wonder about the monocular NVG. Wouldn't it be annoying / irritating having one eye be able to see in the dark, while the other can't?
So the consensus is, don't sign your pre-nup in the field.
