better than the case supplied by Ray Ban
This case is superior to the one supplied by Ray Ban that came with my new prescription sunglasses.  This case securely holds the glasses, a microfiber cleaning cloth, and a couple of premoistened wipes (in their foil packets) and zips closed.  The case is lightweight and unobtrusive. The case could be improved by adding a small loop for attaching to a clip so they don't always burrow to the bottom of a large bag (if they are being transported that way), and the case sides themselves could be slightly strengthened to enhance crush protection.
