Abstract: The process comprises: determining prescribed far vision mean power and addition for each lens of the pair; determining laterality of a wearer; defining a temporal side and a nasal side on each lens of the pair; defining, on each lens being worn and for each gaze direction, a refractive power and a module of resulting astigmatism, each gaze direction corresponding to a lowering angle and to an azimuth angle; defining a proximate vision gaze direction for each lens of the pair; defining, for each lens of the pair, a temporal half-width field of refractive power as the angular distance, at constant lowering angle, between the proximate vision gaze direction and a gaze direction on the temporal side of the lens where the refractive power reaches the value of the prescribed far vision mean power plus three quarters of the prescribed addition; defining, for each lens of the pair, a nasal half-width field of refractive power as the angular distance, at constant lowering angle, between the proximate vision gaze direction and a gaze direction on the nasal side of the lens where the refractive power reaches the value of the prescribed far vision mean power plus three quarters of the prescribed addition; defining, for each lens of the pair, a temporal half-width field of module of resulting astigmatism as the angular distance, at constant lowering angle, between the proximate vision gaze direction and a gaze direction on the temporal side of the lens where the module of resulting astigmatism reaches the value of one quarter of the prescribed addition; and defining, for each lens of the pair, a nasal half-width field of module of resulting astigmatism as the angular distance, at constant lowering angle, between the proximate vision gaze direction and a gaze direction on the nasal side of the lens where the module of resulting astigmatism reaches the value of one quarter of the prescribed addition. The ratio of the difference over the sum of temporal and nasal half-width fields of refractive power and/or the ratio of the difference over the sum of temporal and nasal half-width fields of module of resulting astigmatism are determined for each lens of the pair based on the laterality of the wearer.

Abstract: L'invention concerne un dispositif et un procédé de détermination de l'œil directeur d'un patient (10). Selon l'invention, le dispositif comporte une cible (120), une caméra (110) pour acquérir une image du visage du patient, et un masque (200) à positionner devant le visage du patient. Ce masque comprend : - une paroi d'obturation (210) adaptée à cacher la cible au patient tout en permettant à la caméra de voir le visage du patient, et - une fenêtre de visée (220) de la cible par le patient qui est située au travers de la paroi d'obturation pour permettre au patient de viser la cible avec l'un de ses deux yeux uniquement.

Abstract: Lentille ophtalmique (1) comprenant : - une surface avant et une surface arrière; - un point P de contrôle de la prescription pour une direction de regard (α , &bgr; ) - une zone supérieure qui présente, par rapport au point P, une variation continue de puissance moyenne &Dgr;Pui , monotone entre le point P et le point P , point de maximum de variation en valeur absolue où la valeur signée de variation &Dgr;Pui =Pui (P ) -Pui ( P) est comprise entre -0,1 et -0,4 dioptrie ; - une zone inférieure qui présente, par rapport au point P, une variation continue de puissance moyenne &Dgr;Pui , monotone entre le point P et le point P , point de maximum de variation en valeur absolue où la valeur signée de variation &Dgr;Pui =Pui (P ) -Pui (P) est comprise entre +0,1 et +0,4 dioptrie ; - avec le gradient de puissance moyenne inférieur à 4.10 X &Dgr;Pui , où &Dgr;Pui = |&Dgr;Pui |+ &Dgr;Pui . Une telle lentille permet avantageusement de prendre en compte la dynamique accommodative de l'oeil et d'augmenter le confort visuel du porteur.

Abstract: The lens presents horizontal prismatic refractive power that varies progressively along the main progression meridian (MM') with the addition of horizontal prismatic power being greater than 2 prismatic diopters in absolute value, this addition of horizontal prismatic power being defined by the difference between the horizontal prismatic refractive power at the reference point (L) of the far vision zone and the horizontal prismatic refractive power at the projection point (P') of the reference point (P) of the near vision zone (VP) on the vertical line passing through the reference point (L) of the far vision zone.

Abstract: This method for determining a personalized near vision index for an individual comprises: measuring (10) at least one parameter related to accommodation of the individual; determining (12) a binocular vision model representing vision of the individual; obtaining (14) the personalized near vision index as comprising a binocular visual effort of the individual in near vision, the binocular visual effort being evaluated as a function of the measured at least one parameter related to accommodation and of the determined binocular vision model.

Abstract: The invention relates to a method for determining at least one visual behavior parameter of a person. Said method includes the following steps: a step of encouraging the person to perform a visual test during which he observes at least one target position (30), a step of measuring an item of data that is representative of at least one viewing direction (DR) of the person during said visual test, a step of determining a reference viewing direction (DRM) on the basis of said representative data measured, and a step of positioning, relative to said reference viewing direction, at least one measured target position (50) that is determined, in a reference marker (RCRO) associated with the head of the person, on the basis of said data that is representative of said viewing direction of the person measured during the visual test.
