Abstract: A method of magnetically connecting plastic framed eyeglasses to accessories comprises preparing a primary plastic spectacle frame with thermo-plastically moldable and magnetizable materials injected in designed locations to form plurality of areas integral into the frame by double injection molding. The mating accessory is prepared with magnetizable material sections which at least can partially touch said areas. Said areas or said sections or both are optionally permanently magnetized devices. This inventive method is compatible with many prior art using magnetic clip-ons and can magnetically connect glass lenses directly onto the plastic frame of an optical spectacle without appearing that each spectacle has two lenses. This inventive method can also be used for metal frames, especially for non-magnetizable ones.
