Abstract: Dispositif et procédé de détermination d'un paramètre de réfraction oculaire objective d'un sujet en fonction de directions de regard, ledit dispositif comprenant des moyens de mesure ophtalmologique d'un paramètre de réfraction oculaire objective d'un sujet, et des moyens de stimulation visuelle ayant une proximité variable. Dispositif comprenant des moyens opto-mécaniques d'alignement aptes à effectuer un premier alignement optique de l'axe optique de mesure sur un axe oculaire suivant un premier angle d'abaissement du regard associé à une première valeur de proximité et à un premier angle d'abaissement du regard, et, respectivement, un deuxième alignement de l'axe optique de mesure sur ledit axe oculaire dans une autre position de mesure correspondant un autre angle d'abaissement du regard associée à une autre valeur de proximité et à un autre angle d'abaissement du regard.

Abstract: It is proposed a method for defining a design of an ophthalmic tinted lens (1) provided with a turquoise blue ophthalmic filter (12). It is provided at least one optical parameter value that is prescribed with reference to a clear ophthalmic lens. At least one non-null optical power value is determined from said at least one prescribed optical parameter value. At least one reduction value is obtained. At least one reduced optical power value is calculated in function of said at least one non-null optical power value and said at least one reduction value. The ophthalmic tinted lens design is defined on the basis of said at least one reduced optical power value. Methods for defining a design of a first and a second ophthalmic tinted lens are also proposed. It is also proposed a corresponding ophthalmic tinted lens.

Abstract: L'invention concerne un appareil de mesure de réfraction oculaire subjective comprenant un dispositif de visualisation configuré pour afficher au moins un optotype et un système optique réfractif (11, 21) disposé entre un œil d'un observateur et le dispositif de visualisation, le système optique réfractif ayant une puissance optique variable suivant un pas minimum déterminé. Selon l'invention, le dispositif de visualisation comporte en outre des moyens supplémentaires de variation de puissance optique adaptés pour générer une variation de puissance optique sphérique et/ou cylindrique de manière à ce que le dispositif de visualisation et le système optique réfractif forment une première image de l'optotype avec une première puissance optique totale et, respectivement, une deuxième image de l'optotype avec une deuxième puissance optique totale, la variation de puissance optique entre la première puissance optique totale et la deuxième puissance optique totale étant inférieure au pas minimum déterminé.
