ABSTRACT:
Eyeglasses of a type which permit interchanging of lenses are disclosed which employ a collapsible frame having a pair of hingedly interconnected lens-mounting portions. The lens-mounting portions are configured to engage the peripheral edge of the lens and include several prongs. The peripheral edge of the lenses include prong-receiving recesses which position the lenses relative to the frame to provide secure mounting thereto. The lens-mounting portions of the frame also include a separable connection wherein a mounting lug mounted to one part of the section is received in a socket formed at an end of an opposing section. The separable connection allows the lens-mounting portions to open, facilitating mounting and removal of the lenses, and close so as to provide secure mounting of the lens relative to the frame.
