The present invention relates to a concentric annular ring lens for astigmatism patients, and in particular to a lens for reducing the required number of stock keeping units for a torus product by reducing the susceptibility of the patient to torus angular alignment. Some concentric annular ring lenses consist of a concentric annular ring on one of the front or back faces to calibrate the astigmatism and a toric curve on the reverse surface. The alternating concentric annular ring may have a first optical magnification corresponding to a refractive spherical component of the patient's default prescription Rx and an optical magnification on both of the circumferential magnification of the patient's default prescription Rx or a second optical magnification corresponding to that portion, By dividing the optical band of the contact lens into the region having an intermediate optical magnification, the multifocal toric lens becomes rotationally de-sensitized due to the increase in the visual field depth provided by the plurality of concentric annular rings. Some embodiments of the present invention have a front surface or a back surface of a spherical surface with a corresponding annular annular ring. Some embodiments of the present invention eliminate the torus surface, prism ballast, and slab-off characteristics and provide spherical optical magnification at an intermediate optical power that is intermediate to the base prescription Rx spherical power, the circumferential power formula Rx, the spherical power and the circumferential optical power to provide.
