I also wear a glasses mounted mirror with tri-focals. I've tried progressives and hated the lack of distance peripheral vision (at least in my case) which made me feel unsafe in traffic whether on bike or in car. In addition to the glasses mirror, I also have handlebar mirrors. Your glove mirror, while clever, is right in my glove-back snot-zone. But I may give it a try...I like it. Try the take-a-a-look-mirror. It's not jiggly in my experience.
