1. For glasses we already have a word from “TalkNow! Klingon” (TNK): {mIn QanwI' nguv} “sunglasses” (i.e., “dark eye protectors”) – which implies {mIn QanwI'} for regular eyeglasses.

I would read mIn QanwI' as goggles or some other kind of protective eyewear. Regular glasses aren't for protecting the eye.
