Having gotten a pretty cut up face from a Take-A-Look years back, I won't allow unprotected wire to be intentionally mounted on my face anymore. Once I thought about it, the idea of putting stiff wire right next to my eye is actually pretty terrifying.

I use a Cycleaware Reflex now, which has a round, protected mirror on a breakaway ball mount mounted onto Gumby type wire, and the whole thing is on a breakaway ball mount.
