That's what a helmet mirror is like, except that if you guess wrong or take too long figuring it out, you wreck. Don't do it.
My glasses mirror took me about a week to get used to. After that, adjusting focus and head position for it was an instant reflex. It provides a clearer, more detailed, more stable and wider angle view than a handlebar mirror. Of course, some people's eyes might not work well with them. I also have a convex handlebar mirror for those times when I can't lift my head to use the glasses mirror due to rain, but the handlebar mirror gives a far lower quality view, and requires me to take my eyes off the road ahead for longer.
