Ever since I had LASIK about 10 years ago, I can't go outside without any type of sunglasses on. Overcast days are even bad. So I have been wearing Oakleys. I started with the Half Jackets, moved on to the Flak Jackets, and now I'm wearing the Bottlecaps. I wear them almost everyday, and I've found the Bottlecaps don't dig in the side of my head when I wear a ball cap.
