    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: A device for fitting a handling block to an eyeglass lens to which the handling block adheres temporarily includes a receptacle into which the handling block is push-fitted. An ejector system associated with the receptacle facilitates disengagement of the handling block from the receptacle after it is fitted to the lens. This system is operative outside the receptacle and engages operatively on the eyeglass lens concerned. It comprises two ejector fingers movable parallel to the axis of the receptacle against return springs.
