摘要

As in the lens optimization process, ophthalmic lens designers have usually constructed error functions with 0.5, 0.7, and 1.0 at only three oblique fields. This seems enough to achieve a balanced trade-off with the astigmatic error, the power error, and the distortion all being considered simultaneously. However, for high-power ophthalmic lenses, the aberration curves show serious violations even if aspherical coefficients are involved. The analytical results indicate that a field error suppression of up to 7 points may even be required in some cases. The suppression effects are excellent and examples of both positive and negative lenses are designed.
