ABSTRACT:
A retainer for spectacles has slots formed horizontally from front edges in flat plastic depending rear ends or tips of temples hinged on opposite sides of a double eyeglass frame for receiving and retaining opposite end portions of an elastic band extending around the backside of the user's head to retain the spectacles on the user's head. The slots have forward portions with reduced width relative to thickness of the elastic bands and the width of rear portions of the slots so as to retain the elastic bands within the slots. The rear portions of the slots are beveled so as to reduce wear on the elastic band as well as to enhance the retaining of the band within the rear portions of the slots as well as rendering the band less visible.
