Claim 11:
12. A device for calculating or optimizing a lens or a lens pair, comprising:
a capturer configured to capture a nominal refractive power or a nominal astigmatism at a near reference point of the lens, or of lenses of a lens pair, and
a computer configured:
to determine a correction value of the vertical or horizontal prism at the near reference point of the lens, or of at least one of the lenses of the lens pair;
to modify the nominal refractive power or the nominal astigmatism at the near reference point of the lens, or of the at least one lens of the lens pair, using the previously determined correction value of the vertical or horizontal prism;
to determine a continuous course of the nominal refractive power or of the nominal astigmatism along a main line of the lens using the modified refractive power or nominal astigmatism at the near reference point; and
to calculate or optimize at least one surface of the lens, or of the least one of the lenses of the lens pair, using the modified nominal refractive power or nominal astigmatism at the near reference point and the determined course of the nominal refractive power or of the nominal astigmatism along the main line.
