I don’t mean to sound preachy at all, I just don’t know what your familiarity is with night vision. I used various models a lot during my time in the army so I’m pretty familiar with them (and even though that was over 7 years ago those models are probably archaic).
If I think of something else to add I will but just be real careful that normal/bright light isn’t introduced while you’re wearing them. If you’re inside and a light switch gets flipped on you’ll have a very rough day. Night vision uses what little light there is to illuminate what you’re looking at, so things like moon phase will impact it. So like I said, flipping on a light switch or an errant flashlight to the eyes can be really bad.
Also, depth perception can be a problem while wearing them, so be careful. We used to screw around and try and high-five with them on and the results can be hilarious.
I’m sure you’ll have a lot of fun, just use caution for the areas I mentioned.
