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.
