Summary: | A method for determining an optical function of a progressive ophthalmic lens adapted to a wearer, wherein the method comprises: - providing a prescription of the wearer, - providing wearing data related to specific wearing conditions, the wearing data comprising at least a wearing data parameter having a numerical value, - providing by at least one processor a set of predefined optical functions comprising at least - a first predefined optical function adapted to the prescription of the wearer and to a first predefined value of a wearing data parameter and - a second predefined optical function adapted to the prescription of the wearer and to at least a second predefined value of a wearing data parameter, the second predefined optical function being different from the first predefined optical function, and - determining an optical function of the progressive ophthalmic lens, such that: - when the wearing data parameter has a numerical value greater or equal to, a threshold value, the optical function of the |
