Abstract: The invention relates to a method for determining a progressive ophthalmic device for personalised visual compensation for an individual, according to which the following steps are performed: a) in a first data acquisition phase, determining at least at a first time preceding the appearance of the presbyopia of this individual, at least one value of at least one individual parameter of said individual, and recording each value of the individual parameter of the wearer in a database, in correlation with an associated temporal indicator, b) in a second determination step of the progressive ophthalmic device for personalised visual compensation, determining a desired value of at least one geometric or optical parameter of said progressive ophthalmic device for visual compensation, taking account of said at least one value of the individual parameter determined in step a) and the associated temporal indicator.

Abstract: A progressive ophthalmic lens adapted to a wearer in given wearing conditions having an addition and fulfilling an acuity performance criterion determined by: defining a set of at least three different vision distances including at least a first vision distance greater than or equal to 4 m, a second vision distance greater than or equal to 0.6 m and smaller than or equal to 2 m and a third vision distance smaller than or equal to 0.5 m, each vision distance being associated with an acuity loss threshold value and an acuity area threshold value, providing an acuity model defining acuity loss as a function of lens power and resulting astigmatism, determining of each vision distance using the acuity model the area of gaze directions for which the acuity loss is below the associated acuity loss threshold value.

Abstract: A method for determining at least one optical conception parameter for a progressive ophthalmic lens intended to equip a frame of a wearer, depending on the visual behavior of the latter. The method comprises the following steps: a) collecting a plurality of behavioral measurements relating to a plurality of gaze directions and/or positions of the wearer during a visual task; b) statistically processing said plurality of behavioral measurements in order to determine a zone of use of the area of an eyeglass fitted in said frame, said zone of use being representative of a statistical spatial distribution of said plurality of behavioral measurements; and c) determining at least one optical conception parameter for said progressive ophthalmic lens depending on a spatial extent and/or position of the zone of use.
