ANVIS are certainly nowhere near as rugged as dedicated goggles designed for ground applications, but they’re not made of glass.
They’ve been being used in ground applications for years, however, yes, they broke more often, but it’s not like they break every time you take them out and are a little rough with them, they can survive rough use in many cases, what breaks them is accidents—dropping them, diving enthusiastically through a threshold/window/into a vehicle, etc., is what breaks them. Things that will probably happen, eventually on a long enough timeline, but things that you would normally try to avoid doing even if you had dedicated ground goggles.
But you could use them for many years without issue without babying them, too.
I wouldn’t change the way you use them—except perhaps for being more cautious about using them for prolonged periods of heavy rain—and even so, as I’ve explained before, while they’re not rated for submersion, they do have some water resistance, again, just not as much as ground goggles.
If and when you do break them, there are alternative housing options you can swap them over to fairly easily. I would just use them as normal until then.
