While inactive they're no more distracting than a pair of regular glasses and while using them for navigation they're significantly less distracting than using a traditional GPS.
I personally fall on the other side; why not extensively test before banning. We live in a society that jumps to conclusions. I believe we should have a proper understanding of something before deciding to make laws relating to it. What about the positive benefits. Also, do you really expect them to do the research after banning it? Look how long it has taken the FAA to even start reducing the ban on mobile devices.
In my opinion, they are far safer to wear and use for the purpose of navigation than a phone or mounted GPS. They give me the necessary information quickly and don't require me to adjust my vision off the road.
