Abstract: The disclosure relates to a method for detecting a variation of a current refractive error of a person. The method comprises obtaining (SI) an optical equipment comprising an optical lens, a dioptric function of the optical lens being adapted for correcting an initial refractive error of a person, the optical equipment further comprising a processing circuit comprising a processor operably connected to a memory. The method comprises using the memory, obtaining (S6) a current value of a parameter, the current value being indicative of a variation of a current refractive error of the person with respect to the initial refractive error. The method comprises using the processing circuit, detecting (S7) a variation of a current refractive error of the person with respect to the initial refractive error based on the obtained current value of the parameter.

Abstract: A method for determining a design of a progressive lens intended to be worn by a future wearer, the progressive lens comprising a front surface and a back surface, at least one of the front surface and the back surface comprising a progression profile on its general spherical shape, said at least one progression profile defining a meridian line extending from a distance-vision point to a near-vision point, said meridian line comprising a vertical portion passing through the distance-vision point and an inclined portion passing through the near-vision point, the vertical portion and the inclined portion forming an angle between them, the method comprising: obtaining first data representative of a first measurement of a first postural instability of the future wearer when seeing a visual pattern moving along an mediolateral direction, determining a repartition between the first progression profile and the second progression profile based on the first data.

Abstract: An ophthalmic device (10) is proposed for reducing dyslexia effects for a wearer (20), comprising: - a frame intended to be worn by the wearer (20), - a blinking illuminating element (14) coupled to the frame comprising at least one light source configured to emit light in front of the wearer's head so as to lighten a medium (18) observed by the wearer (20), said at least one light source being configured to be successively switched on and switched off at a predetermined frequency when the blinking illuminating element (14) is activated.

Abstract: Un procédé de caractérisation d'une perception de flou par un sujet (10) permet de déterminer une valeur de flou dioptrique pour une image (C) qui est observée par le sujet. L'image possède un flou produit par filtrage passe- bas de composantes d'image, en fonction de fréquences spatiales respectives des dites composantes d'image. Une indication de sa perception du flou dans l'image est fournie par le sujet, et est associée à la valeur du flou dioptrique. Plusieurs images associées à des valeurs différentes de flou dioptrique permettent d'encadrer une valeur-seuil du flou dioptrique pour le sujet, qui correspond à un critère de perception du flou. Le procédé permet d'ajuster le design d'un verre progressif qui est destiné au sujet en fonction de la sensibilité dudit sujet au flou visuel.

Abstract: Une réalisation d'un verre de lunettes progressif permet de personnaliser le verre en fonction d'une perception de flou d'un futur porteur du verre. Pour cela, une valeur-seuil (VS) du flou est déterminée pour le porteur, selon un critère de perception du flou qui varie en fonction d'une valeur d'addition de puissance optique prescrite pour le porteur. La valeur-seuil du flou est associée à une direction de regard de référence pour le verre qui est fourni au porteur.

Abstract: A method for providing a spectacle ophthalmic lens to a wearer, the method comprising the following steps: providing a value, SV, representing the sensitivity of the wearer referred to a scale of sensitivity to perception of spatial orientation, according to both visual and non visual frames of reference; calculating a design of the spectacle ophthalmic lens or selecting a design in a spectacle ophthalmic lens design data base by adapting the management of residual astigmatism and/or optical power repartition according to gaze direction based on the value, SV, representing the sensitivity of the wearer referred to a scale of sensitivity to perception of spatial orientation.
