Make it a trio. I find it easier to just take my glasses off. I am mildly nearsighted, so I can get by without glasses, but I lose details at about 40 feet out. So if I want to enjoy the view when I'm not shooting I've taken to wearing them and taking them off to shoot. You'd think by now I'd have gotten something where I can just drop them around my neck, but no, I just bite the arm. My normal glasses darken outdoors making them useless for photography, so I have a pair of glasses that I wear when shooting, and in truth these sit a little closer to my eye (flexible metal frame vs. horn-rimmed) and I don't have too much of an issue with them and my D600. With the D7000 it's a little more problematic, but I can adjust.
My real issue is that I have some floaters in my eyes that make manual focus a royal pain when I need to do it.
