    摘要: A toric multifocal lens (10, 26) including a plurality of vision correction regions (12, 14, 28, 30) having centers on a common optical center axis, the plurality of vision correction regions providing respective different values of a spherical optical power, each of the plurality of vision correction regions having an optical power for correction of astigmatism, wherein the improvement comprises: at least one of a cylindrical optical power and a cylindrical axis orientation which determine the optical power for correction of astigmatism being different in at least two different vision correction regions of the plurality of vision correction regions, so that the at least two different vision correction regions have respective different values of the optical power for correction of astigmatism.
