YAS.
I've got my favourite pair of red framed glasses that I love to wear, but they're cheap.  I got them at WalMart, but I love them.  They always fall down the bridge of my nose -- I'm a regular at my eyeglass store to get them tightened up.  It's SUPER annoying when I'm working out at the gym.  Anything like a plank or burpees or whatever causes my glasses to slide off.  Yoga?  Fuhgit abaht it.  Introduce NerdWax!  Although hot yoga, I still take them off, everything else, it stays in place.  I love this stuff.  Hilarious packaging, so that's always a plus.
