ABSTRACT:
The present invention provides an eyeglass retainer headband comprised of a tube of pliable material having two open ends, a tube segment at each end being turned into itself to form a double walled end portion of somewhat reduced inner diameter and increased stiffness while also providing a smoothly contoured or finished edge around each opening of the tube to prevent fraying of the fabric. Although it is presently preferred that the tube be made of a knitted fabric, the invention is not restricted to such material and may extend to other pliable elastic materials.
