A visual aid device is shown for use by a wearer. The device includes a spectacle frame with a pair of carrier lenses mounted on the spectacle frame, each of the lenses having an aperture for receiving a bushing which protrudes through the lens. A bushing is fixedly mounted in each aperture at a predetermined inclination and declination. A quick release mount within each bushing allows the bushings to receive a variety of interchangeable optical devices.
