Here is a wonderful rimless Bling fashion accessory for your eyes! Lovely Swarovski crystal rimless readers are here for helping you read more clearly as well as showing everyone else that you are a trendy modern woman! These have silver metal frames and are very light weight! "AB" stands for Aurora Borealis which has a property of casting different reflective lighting with that chosen crystal color. If it doesn't have AB, the color reflects beautifully on its own. These Silver frames in a catalog recently were priced at $30.00 for readers w/out crystals, much less Swarovski crystals!
