Abstract:
A method of calculating a shaping setpoint for an ophthalmic lens along a longitudinal profile includes: an operation of acquiring an initial longitudinal profile; an operation of centering the initial longitudinal profile on the lens; an operation of searching for two remarkable points of the initial longitudinal profile as a function of determined criteria; an operation of calculating a modified axial coordinate for each remarkable point in order to ensure proper mounting and esthetic appearance of the lens in its eyeglass frame; and an operation of calculating a final longitudinal profile resulting from a transformation of the initial longitudinal profile that is such that the final longitudinal profile passes through the two remarkable points.
