Title (EN) SYSTEMS AND METHODS FOR FITTING CONTACT LENSES
(FR) SYSTÈMES ET PROCÉDÉS D'AJUSTEMENT DE LENTILLES DE CONTACT
Abstract:
(EN) Fitting systems and methods and software and calculators are provided that measure and/or use two or more pre-determined clearance preference values from specific observation points or chords of the lens, and make two or more observations of clearance of the lens from the eye. By using the difference between the pre- determined clearance preference values and the observations at the specific observation points to modify the disclosed sagittal depths of at least two zones, a final lens is selected. In accordance with various embodiments of the present disclosure, a landmark indicator may be provided on a contact lens to assist the observation of clearances of two or more chords of a lens or eye.
(FR) L'invention concerne des systèmes et des procédés et des logiciels et des calculateurs d'ajustement qui mesurent et/ou utilisent deux valeurs de préférence de distance prédéterminées ou plus à partir de points ou de cordes d'observation spécifiques de la lentille, et effectuent deux observations ou plus de distance entre la lentille et l’œil. En utilisant la différence entre les valeurs de préférence de distance prédéterminées et les observations aux points d'observation spécifiques pour modifier les profondeurs sagittales décrites d'au moins deux zones, une lentille finale est sélectionnée. Selon divers modes de réalisation de la présente invention, un indicateur de repère peut être disposé sur une lentille de contact pour faciliter l'observation des distances de deux cordes ou plus d'une lentille ou d'un œil.
