Patent

CA 2675040

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.

L'invention concerne dans un aspect un procédé de correction de la vision qui utilise deux lentilles, au moins une desquelles est une lentille multifocale, présentant différentes caractéristiques de focalisation pour une utilisation sur les deux yeux du patient. La performance visuelle de chaque lentille (par exemple, le contraste ou l'acuité visuelle) est sélectionnée conformément à une relation prédéfinie de sorte à optimiser la performance visuelle binoculaire fournie par la combinaison des lentilles.
