Abstract
Disclosed is a method for determining an optical function of a progressive ophthalmic lens for a wearer, including: providing a prescription of the wearer; providing wearing data including at least a numerical parameter; providing by at least one processor a set of predefined optical functions including at least a first predefined optical function adapted to the prescription of the wearer and to a first predefined wearing parameter and a second predefined optical function for the prescription of the wearer and to at least a second predefined wearing data parameter, the second predefined optical function being different from the first; and determining an optical function of the progressive ophthalmic lens, so: when the wearing data parameter≥a threshold value, the optical function of the lens=first predefined optical function, and when the wearing data parameter<the threshold value, the optical function=the second predefined optical function.
