Abstract
Abstract Eyeglass frames having a plurality of circular, multi-colored lenses pivotably mounted thereon so that different colored lenses may be rotatably interchanged in front of the eyes of the wearer of the glasses. The lenses are mounted in a frame which has a small, rounded projection protruding from the edge thereof, adjacent each lens which snaps into a pair of projections provided on the nose bridge of the eyeglass frames in order to lock the lenses into position. The eyeglass frames are pivotably connected above the nose bridge of the eyeglasses in order to allow easy folding of the eyeglasses into a planar configuration.
