Abstract
The embodiments of the present invention provide new and unique plastic folding and telescoping eyeglass frames that provide the opportunity for producing a wide variety of colorful, lightweight and easy folding eyewear. Although the illustrated plastic folding and telescoping eyeglasses appear to be the fragile plastic styles of the past, they possess far greater flexibility and fracture resistance due to new cross-linked polymer plastics used in injection molding processes. The frames are easily adapted to the extreme curvature of some of the lenses of trendy eyeglass fashions and facilitated by the inclusion of a bi-folding bridge member. The plastic folding and telescoping eyeglasses also incorporate telescoping temples. An off-set bi-folding bridge member permits the lenses to fold over one another and the temples to rest next to one another providing a compact package for easy storage.
