ABSTRACT:
A weight for use on a spectacle frame and a method of attaching in which a high density weight is provided which is relatively short in length and which has a slot-like recess in one side for receiving a portion of the rearward part of a spectacle bar is receivable. The weight is preferably cemented to the bar in a desired location rearward of the ear and counterbalances at least a portion of the weight of the foward lens-holding part of the frame. Alternatively, the weight can be adhered to the outwardly facing side of the rearward end of the side bar or earpiece of a spectacle frame. The weight is so attached to the side bar of the frame as to provide the greatest comfort to the wearer.
