PROBLEM TO BE SOLVED: To provide an optical lens polishing method capable of excellently polishing the entire face to be polished of non-rotational symmetry. SOLUTION: The optical lens polishing method comprises a step S1 of calculating and identifying the axial direction in which the mean curvature of a face to be polished of a lens is minimum, a step S2 of mounting the lens on a polishing device so that the axial direction in which the mean curvature of the face to be polished of the lens is minimum is matched with the major axial direction of a polishing tool, and a step S3 of polishing the face to be polished with the track-less polishing locus with the polishing locus being slightly deviated for each turn by performing the oscillating and turning motion of the polishing tool and a polishing pad while the face to be polished of the lens is brought into contact with a polishing pad, reciprocating the lens in the axial direction in which the mean curvature of the face to be polished is minimum, and in the direction orthogonal to the axial direction.
