发明名称 Eyeglass stem holder
摘要 An eyeglass retainer which is an elongated band of stretchable material formed to have a pair of oppositely positioned tubes, each of which tubes can receive a portion of an eyeglass frame. The tubes are formed from two materials of differing stretchability to promote the gripping of the eyeglass frame inserted therein. The innermost ends of the tube may be sealed to prevent the eyeglass frame from passing completely through the tube. The sealing of the innermost tube end provides a self adjusting eyeglass retainer.
