ABSTRACT:
Eyeglasses for intermittent use which can be flat folded and flipped up when not in use, include a cross-bar which extends the width of the eyeglasses. A lens plate is rotatably mounted to the cross bar. Right and left temples extend substantially perpendicularly from opposite ends of the cross bar and are rotatable relative to the lens plate. The temples are composed of a lower temple piece and a temple piece extension. The lower temple pieces extend substantially perpendicularly from opposite ends of the cross-bar. The temple piece extension is rotatably connected to the lower temple piece by for example, a pivot. A nose bridge is located in the middle of the cross bar and is rotatably mounted to the cross bar independent of the rotation lens plate.
