ABSTRACT:
A variable density light-polarizing spectacles apparatus comprising a frame having right and left lens carrier portions, a bridge portion, and rearwardly directed temples for supporting the spectacles apparatus before the eyes of the wearer. Inner right and left lenses are rotatably mounted within the right and left lens carrier portions, respectively. Each inner lens has a notched portion at its periphery. A gear assembly is positioned substantially between the right and left lens carrier portions of the frame. The gear assembly meshes with the notched portion of the inner lenses to allow for the simultaneous rotation of the inner right and left lenses. The frame has an upwardly-facing opening substantially above the bridge portion. A portion of the gear assembly extends slightly beyond the upwardly facing opening of the frame to permit manual adjustment of the orientation of the inner lenses. A removable, outer lens assembly slidably engages the frame.
