Abstract: Method for determining a dioptric parameter of a person, for example of an ophthalmic lens to be provided to a person, the method comprising: - a set-up step, during which a test optical element having a dioptric function having a specific value of the dioptric parameter to be determined is provided to the person and the person is required to look at a visual target using the test optical element, - a data collecting step, during which evaluation data and certitude data are collected, the evaluation data being indicative of the visual assessment expressed by the person looking at the visual target using the test optical element and certitude data being indicative of the degree of certainty of the person upon expressing the visual assessment, wherein the set-up and data collecting steps are repeated by varying the value of the dioptric parameter of the test optical element, and the method further comprises: - a global analyzing step, during which for each value of the dioptric parameter tested during the set-up and data collecting step a value a degree of certainty of the person is determined and the value of the dioptric parameter of the person is determined based on the values of degree of certainty of the person.

Abstract: L'invention concerne un dispositif et un procédé de détermination d'un paramètre de réfraction oculaire objective d'un sujet en fonction d'une pluralité de directions de regard du sujet, 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 et destinés à stimuler l'accommodation visuelle du sujet pour une première et une deuxième valeurs de proximité. Selon l'invention, le dispositif comprend des moyens opto-mécaniques d'alignement aptes à effectuer un premier alignement optique de l'axe optique de mesure sur un axe oculaire dans une première position de mesure correspondant à un premier angle d'abaissement du regard associé à une première valeur de proximité de manière à effectuer une première mesure d'un paramètre de réfraction oculaire objective dudit sujet et lesdits moyens opto-mécaniques d'alignement sont aptes à effectuer 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 de manière à effectuer une deuxième mesure.
