Method and device for measuring data for fitting an ophthalmic lens in a frame for a given individual
27 Sep 22
Disclosed is a method for measuring data for fitting an ophthalmic lens in a frame for a individual, including the following steps: a) placing the individual in a natural posture; b) displaying a visual target with adjustable position in the field of view of the individual; c) having the individual equipped with the frame adjust the position of the visual target in order to place it straight ahead from him; d) determining the intersection, with a surface representative of the lens once placed in the frame, of the line of sight of the individual looking at the visual target with its adjusted position and determining the data based on the intersection determined.

Method for determining a progressive ophthalmic device for personalised visual compensation for an individual
27 Sep 22
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.
