Abstract
An accessory eyeglasses retention device is integrally formed as a single elastomeric piece to secure eyeglasses to a wearer's head. The accessory eyeglasses retention device may include an elongated body extending between a front end and a back end, an adjustment mechanism including a first elastic strap and a second elastic strap, for example, longitudinally spaced apart on the elongated body and configured to hold a temple of the eyeglasses and adjustably position the elongated body relative to the temple. An angled flap is at the back end of the elongated body, extending and angled in a direction towards a portion of the wearer's head when the eyeglasses are worn on the wearer's head, and configured to securely retain the eyeglasses in a desired location on the wearer's head. Also, a lanyard attachment feature may be included at the back end of the elongated body and configured to attach the elongated body to an eyeglasses lanyard.
