摘要：

Local wavefront distortion by the total refractive system of the eye is measured by a variant of the Scheiner principle at some thirty loci of 1 mm diameter. At each locus we find the normal to the wave front that could form a point focus. A simple visual display is used to review the data, and a steepest descents fit of the wavefronts with a power series enables comparison with more traditional measures of refractive error.
