Abstract
Eyewear having a temple that provides for adjustment of the temple length and adjustment of the pantoscopic angle of the eyewear. The eyewear lens includes a plurality of projections that define various pantoscopic angles. A temple endpiece includes a set of recesses that engage the projections formed on the lens. The temple endpiece is rotated relative to the lens to set the pantoscopic angle. A groove is formed in an endpiece head to allow distal ends of the head to flex away from the lens and reduce the pressure on the lens.
