Abstract: Measurements are made on the distance (15) between upper and lower horizontal tangents (17,16) to the left- and right-hand spectacle frames (2,3), the overall width (14) of each frame, the interpupillary spacing (7) and its division (8, 9) by the axis of the nose (6), the distance (12) between the frames, and the heights (18, 19) of the pupils of both eyes (4, 5) above the lower tangent (16). The centre of each pupil is located automatically by analysis of the luminance gradient, and the tangents are determined from luminance gradient analysis and frame contour extn..

Abstract: Mensurating device comprising at least one photosensitive sensor (16) providing a front view in order to take into account front-related parameters. According to the invention, the mensurating device further includes data acquisition means (16, 28, 29, 27) for taking into account at least one additional side-related parameter. Application in fitting spectacles to a patient.
