Abstract
In one aspect, the present invention provides a method for correcting vision that employs two lenses, at least one of which is a multifocal lens, with different focusing characteristics for use in the two eyes of the patient. The visual performance of each lens (e.g., visual contrast or acuity) is selected in accordance with a predefined relation so as to optimize the binocular visual performance provided by the combination of the lenses.
