Eyeglass Ear Grips

I got my nose pierced yesterday only to find out that my glasses were slipping down my oily nose and pinging my new piercing. Rude! My smart pal Noelle recommended these guys, I overnighted them (sorry they're from the big A, but I did a search and couldn't find them anywhere else) and they completely fixed my problem. My glasses have stayed firmly in place all day! And for $6, why not?
