Toric multifocal lens having different astigmatism corrective optical powers in respective vision correction regions, and method of producing the same
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.
摘要（中）：

复曲面多焦点镜片（10，26）包括具有一个共同的光学中心轴的中心视力校正区的多元性（12，14，28，30），提供了一个球面光焦度的respectivement不同值视力校正区的多元性， 每一个都具有一种用于散光的矫正光焦度的视力校正区的多元性，worin改进之处包括的：一个柱面光焦度中的至少一个和一个圆柱轴取向，这确定性矿散光的校正在至少两个是不同的光功率 视力校正区的多个不同的视力矫正的区域，从而DASS死至少两个不同的视力校正区域已为矫正散光respectivement的光功率的不同的值。
