ABSTRACT:
Earstems for eyewear are configured to define a lateral distance between the earstems which is greater than the width of the head in the anterior temple region so as to prevent any contact of the earstems and the head in that region. Preferably, the earstems include a diverging section, a transition section, a converging section and a retaining section, wherein the transition section defines the greatest lateral distance between the earstems. The retaining section extends posteriorally from the converging section so as to provide an interfacing surface between the eyewear and the head. The retaining section may be configured so as to accommodate the traction device so as to enhance the retention of the eyewear about the head by increasing the coefficient of static friction between the eyewear and the head.
