Abstract
A pair of eyeglass frames are provided having two wrap-around temple portions, and a temple-portion adjustment mechanism. The two wrap-around temple portions pivotally attach to the frame. Each wrap-around temple portion includes a substantially straight portion and a resilient, wrap-around portion connected thereto. The curved portion has a bias to wrap around a wearer's ear. The temple-portion adjustment mechanism includes a beam which may rigidize a selected length of the corresponding wrap-around temple portion. The wearer selects the length rigidized by sliding the beam along an axis of the straight portion. Sliding the beam in a first axial direction draws a length of the wrap-around portion into engagement with the beam and counteracts the bias in the curved portion. This straightens and rigidly supports the selected length of the curved portion.
