Abstract
The invention relates to a method for determining at least an optical feature of an ophthalmic lens to be placed in a frame for vision correction of a subject, comprising: a) measuring (100) a value of a fitting parameter linked to the subject and/or the frame or a value of a dioptric parameter of the subject, thanks to a measurement process, b) providing (200) a level of uncertainty of said value measured in step a) depending on said measurement process, c) determining (400; 510; 620; 640) said optical feature of said ophthalmic lens by taking into account said value measured in step a) and said level of uncertainty provided in step b).
