1. A method of measuring at least one geometrico-physiognomic parameter (H, TETA) for positioning a vision-correcting eyeglass frame ( 10 ) on the face of a wearer for personalized calculation and/or mounting of corrective lenses associated with said frame, including a step of using an image-capture appliance ( 1 ) to capture a digital image substantially in front view of the wearer's face wearing at least the frame ( 10 ), and a step of calculating the geometrico-physiognomic parameter (H, TETA) on the basis of processing the captured image, the method being characterized in that the calculation of the geometrico-physiognomic parameter (H, TETA) includes identifying, in the image, the image of a predetermined remarkable point (RC) that is directly or indirectly associated with the wearer's face or with the frame, and it takes into consideration a magnitude representative of the absolute vertical angle of observation (GAMMA) formed between firstly an observation line (DO) connecting the pupil ( 7 ) of the image-capture appliance ( 1 ) to the remarkable point (RC), and secondly its projection onto a horizontal plane (PF).
