Third-order equations are developed giving sagittal and tangential power errors corresponding to the eye rotating to look through the periphery of a spectacle lens. The equations are applicable for conicoid aspherical surfaces. From these, other equations are derived for elimination of oblique astigmatism and mean oblique error. Graphical examples show how aspherizing either lens surface affects the lens bendings required to eliminate oblique astigmatism.
推导了三阶方程，给出了与眼睛转动以透过眼镜镜片边缘视物相对应的矢状和切向屈光力误差。这些方程适用于二次曲面非球面。由此，推导出了其他用于消除斜向散光和平均斜向误差的方程。图形示例展示了对任一镜片表面进行非球面化处理如何影响消除斜向散光所需的镜片弯度。
