• obtaining a spectacle parameter configured to adapt spectacles to a head of a person with the head of the person being in a first head posture;
• displaying a representation of the head in the first head posture or a representation of the head with a spectacle frame in a first spectacle frame alignment;
• determining an angle of inclination of the head of the person in the corrected head posture compared to the first head posture or the angle of inclination between the first spectacle frame alignment and the corrected spectacle frame alignment,
• wherein the spectacle parameter includes an axis position of a spherocylindrical refraction, and wherein the correction of the axis position includes a registration of the irises of the eyes in an image of the head when determining the spherocylindrical refraction and the irises of the eyes in an image of the head in the first head posture when measuring a centration parameter;
• obtaining a corrected axis position of the spherocylindrical refraction by correcting the obtained axis position of the spherocylindrical refraction in an amount of the determined angle of inclination;
• and
• providing the corrected axis position of the spherocylindrical refraction for a production of a spectacle lens.
