Over high tea yesterday I happened to mention that I was wearing my spare pair of glasses because of an accident to my main pair. I said that the part of my glasses that goes from the edge of the lens to my ear had broken.

I naturally referred to this as the leg of my glasses. My companions were an English woman who insisted that the word was arm, and two Canadians (one male and one female if that's relevant), who were equally vehement that the word was temple.

Any other possibilities?
