Abstract

Methods and devices for correcting centering parameters and/or an axial position of a spherocylindrical refraction on the basis of a habitual head position are disclosed. A representation of the head of a user in a head posture or a representation of the head with a spectacle frame in a spectacle frame alignment are displayed. To correct the spectacle parameter based on a corrected head posture and/or a corrected spectacle frame alignment, the corrected head posture and/or the corrected spectacle frame alignment is determined by at least partially manually correcting a head posture in the displayed representation of the head and/or of the spectacle frame alignment in the displayed representation of the head with the spectacle frame. A representation of the head of a user is shown on a display, thereby allowing intuitive adjustment of a habitual head position.
