Method for determining a progressive ophthalmic device for personalised visual compensation for an individual

A method for determining an item of personalized visual-compensation progressive ophthalmic equipment for an individual the method comprising:

• a) in a data-acquiring first phase, at at least one first moment preceding an appearance of presbyopia of the individual, determining at least one value of at least one individual parameter of the individual, and recording each value of the plurality of values of the individual parameter of the individual in a database, in correspondence with an associated temporal indicator;
• and
• b) in a second step of determining the item of personalized visual-compensation progressive ophthalmic equipment, determining a value of at least one geometric or optical parameter of the item of visual-compensation progressive ophthalmic equipment while taking into account the at least one value, determined in step a), of the individual parameter and the associated temporal indicator, wherein
• in step a), determining and recording a value of at least one control parameter relating to the individual and in the database, in correspondence with the at least one value of the individual parameter and the corresponding temporal indicator,
• in step b), weighting an importance of the at least one value of the individual parameter determined in step a) depending on the value of the associated control parameter,
• in step a), determining a plurality of values of the individual parameter, and
• in step b), an importance of each value, determined in step a), of the individual parameter is weighted depending on a variation over time in the control parameter.
