PROBLEM TO BE SOLVED: To provide a method for manufacturing a slip-off preventive spectacle frame which does not form the traces of slip-off preventers at the ridge of the nose and allows the light wearing of spectacles in order to prevent the traces of the slip-off preventers from being formed at the ridge of the nose and to prevent the exertion of burden on beauty of women when the conventional spectacles are used. SOLUTION: The slip-off preventers are mounted at the horizontal main shafts (frame) of the right and left temples of the spectacles (lenses) to prevent the formation of the trances of the slip-off preventers at the ridge of the nose in using the spectacles. Since the spectacles are not put on the ridge of the nose, the burden is not exerted thereon. The spectacles may be lightly worn. The slip-off preventers are formed by mounting magnets in the parts in contact with the temple to improve the circulation of the blood and to prevent the fatigue of the eyes.
