Ahh nightvision, thats a simple effect to achieve if you know what your doing, ive tryed a few times and i have no idea what im going ;D but ive come close. This is what ive done:

I have a night vision scope so I was able to use that, and some pictures for references. I should have put in more grain however.
I like your edits, but not so much green next time ;D
Edit:
Just noticed one of your shots way looking at the sun youll need some of these---

if you ever plan on seeing after doing that ;)
