Title
(EN) VERGENCE DETECTION METHOD AND SYSTEM
(FR) PROCÉDÉ ET SYSTÈME DE DÉTECTION DE VERGENCE
Abstract
(EN) A vergence detection system is incorporated into an ophthalmic lens to automatically determine if the lens wearer is trying to accommodate by viewing a near object or gazing into the distance to view a far object by measuring the vergence angles as the wearer is trying to see near or far. The vergence detection system utilizes multiple sensors to measure certain parameters and make a calculation to determine vergence.
(FR) Un système de détection de vergence est incorporé dans une lentille ophtalmique pour déterminer automatiquement si le porteur de la lentille essaie de s'adapter par la visualisation d'un objet proche ou en portant le regard au loin pour visualiser un objet éloigné, en mesurant les angles de vergence lorsque le porteur essaie de voir près ou loin. Le système de détection de vergence utilise de multiples capteurs pour mesurer certains paramètres et effectuer un calcul pour déterminer la vergence.
