Your eyeballs are always wet anyway. You have these wonderful built in biological windshield wipers called "eyelids."
You'll probably find you have to carry eye drops anyway, because if you're going to have any problem at all with moisture, it will be not enough of it.

I'm not likely to be around much longer. As before when I first signed up here years ago, I'm finding that after a long hiatus, and after only a few days back on here, I'm spending way too much time here again already. So I'm requesting my account be locked, banned or whatever. It's just time. Until then, well, I dunno...
