  • Patent number: 5537765
    Abstract: An identification tag for eyeglasses, spectacles and the like is formed from a flexible member having two opposed end portions and a central portion disposed therebetween. Each end portion has a pair of slots and ribs in parallel arrangement with each other. The slots and ribs are perpendicular to a longitudinal axis of the member. A peripheral edge of the tag is narrower at the central portion of the tag. The parallel slots and rib members coact for receiving a stem portion of an eyeglass frame to maintain the tag at a select position on the stem. An end portion of the tag can be folded back over on itself so that the slots at that end portion are brought into registration with each other for receiving the frame stem which is threaded through the aligned slots.
