Abstract
A magnetically attached spectacle lens wherein magnets are embedded in the rear surface of the lens in a circumferential groove near the periphery of the lens. The magnets are spaced around the periphery of the lens, and are held in the groove by preferably a wicked in cyanoacrylate adhesive. The spaces between the magnets are preferably filled with a light activated potting compound. Prior to installation of the magnets, the inside of the groove is painted, preferably by spraying, with an opaque paint whereby the magnets are hidden from the view of onlookers. During fabrication, after magnet installation, any overspray from the painting step is removed by using a solvent preferably applied by moistened swabs or cloth.
