(About to be) First-Time NV Owner Tips

Currently waiting on an Elbit Omni 7 PVS-14 to arrive (LETS GOOOOOOOO) and I’m already paranoid about how I should maintain it. I know these are milspec devices and not really “fragile” but what are some dos and don’ts that I should be aware of? I’m mainly worried about the tube, of course. Should be avoiding streetlights? Brighter city lights in the distance? Full moons? Am I overthinking because I just spent $1800 on a toy to make me less scared when I’m hiking in the woods? You tell me.
