Patent

CA 2629906

A method of designing and/or selecting a progressive addition lens design for a wearer is disclosed. In an embodiment, the method includes displaying a graphical representation of an initial progressive addition lens design including design parameters having design values. A user interface is provided including, for each of one or more of the design parameters, a control that is adjustable over a range of levels, each level in the range being associated with a corresponding value of the respective design parameter. A control is adjusted to select a level and the selection is processed so as to substantially simultaneously update the displayed graphical representation in accordance with the selected level to provide a modified progressive lens design. A system for designing and/or selecting a progressive addition lens design for a wearer is also disclosed.

L'invention concerne un procédé de conception et/ou de sélection de lentille à addition progressive destinée à un utilisateur. Dans un mode de réalisation, le procédé consiste à afficher une représentation graphique d'une conception de lentille à addition progressive initiale comprenant des paramètres de conception qui présentent des valeurs de conception. Une interface utilisateur comprend, pour un ou plusieurs paramètre(s) de conception, une commande qui est réglable dans une gamme de niveaux, chaque niveau de la gamme étant associé à une valeur correspondante du paramètre de conception respectif. On règle une commande afin de sélectionner un niveau et on traite la sélection afin de mettre sensiblement simultanément à jour la représentation graphique affichée en fonction du niveau sélectionné afin de fournir une conception de lentille à addition progressive modifiée. L'invention concerne également un système de conception et/ou de sélection de conception de lentille à addition progressive destinée à un utilisateur.
