I wear wrist bands simply because sweat runs down my arm and fills my brifters with sweat. I really need something that I can shove under my glasses. Taking my glasses on/off is not smooth with glasses rims, ears, helmet straps, and headband stuff all in the same space. But that is with thin wire rims (prescription). Maybe with heavier rims I could just bully the glasses behind my ears (once every 45 seconds).
