Abstract

A vision simulation, on assumption that spectacles are worn, is performed for a first model designed by setting a target additional power of a desirable value at a position corresponding to a fitting point on a principal meridian. A correction amount is computed for correcting the difference between a simulation value obtained for the additional power at the position corresponding to the fitting point on the principal meridian through the vision simulation and the target additional power. A second model is designed by replacing the additional power with a value obtained by the addition of the calculated correction amount to the target additional power.
