FIELD: physics.
SUBSTANCE: invention discloses a set of lenses for correcting the vision of a patient, having two lenses for use in two eyes of the patient, wherein the lenses have different focusing characteristics to provide the patient with binocular visual performance in the selected range. At least one of the lenses is a multifocal lens, and visual performance of each lens (e.g., visual contrast or visual acuity) is selected according to a disclosed predetermined relationship in order to optimise binocular visual performance provided by the lens combination.
EFFECT: improved binocular vision.
