Title
(EN) METHOD FOR DETERMINING A PROGRESSIVE LENS AND ASSOCIATED SYSTEM
(FR) PROCÉDÉ DE DÉTERMINATION D'UNE LENTILLE PROGRESSIVE ET SYSTÈME ASSOCIÉ
Abstract
(EN)
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 at a visual pattern moving along an anterior-posterior direction; • determining the angle of the inclined portion based on the first data.
(FR)
Procédé de détermination d'une conception d'une lentille progressive destinée à être portée par un futur porteur, la lentille progressive comprenant une surface avant et une surface arrière, au moins l'une parmi la surface avant et la surface arrière comprenant un profil de progression sur sa forme générale sphérique, dont au moins un profil de progression définissant une ligne méridienne s'étendant d'un point de vision de distance à un point de vision de près, ladite ligne méridienne comprenant une partie verticale passant par le point de vision de distance et une partie inclinée passant par le point de vision de près, la partie verticale et la partie inclinée formant un angle entre elles, le procédé comprenant • l'obtention des premières données représentatives d'une première mesure d'une première instabilité posturale du futur porteur lors de la visualisation d'un motif visuel se déplaçant le long d'une direction antérieure-postérieure ; • la détermination de l'angle de la partie inclinée sur la base des premières données.
