These aren't very attractive, but I needed a case to fit my Solar Shield sunglasses.  The Solar Shields fit over my regular glasses so they are quite large and needed a case this large.  I was very happy to find that they fit.  I also bought a case that is designed to hold two pairs of glasses.  That style also fit ONE pair of my sunglasses. I hope that helps those of you with large glasses.  Make sure you measure!
