摘要： The invention relates to a method of shaping an ophthalmic lens to have a desired outline (11) by means of a machining device including a blocking support for the ophthalmic lens and at least one first machining tool, the method comprising the steps of: obtaining an inner cutting limit (12) for said first machining tool; defining an initial blocking position (P1) for the ophthalmic lens and its desired outline; calculating whether at least a portion of the desired outline presents a non-zero intersection (Q21-Q22) with said inner cutting limit; defining as the final blocking position (PF) either the unchanged initial blocking position if the intersection calculated the calculation step is zero, or else a blocking position that is modified relative to the initial blocking position so that the desired outline as repositioned using the modified blocking position does not present an intersection with the inner cutting limit associated with the first tool; and blocking and shaping the ophthalmic lens with the desired outline.

摘要： A method of shaping an ophthalmic lens for mounting in a mixed surround of an eyeglass frame that presents at least one half-rim, includes: a) a step of acquiring a longitudinal profile characterizing the shape desired for the outline of the lens; b) a step of subdividing the longitudinal profile into a first arc associated with the half-rim and a second arc, in which step the positions of two singular points of the longitudinal profile are acquired that characterize the positions of the two ends of the half-rim; c) a first step of finishing the ophthalmic lens, during which a first portion of its outline is brought to the shape of the first arc; and d) a second step of finishing the ophthalmic lens, during which a second portion of its outline is brought to the shape of the second arc. In step b), the position of at least one of the two acquired singular points is corrected so as to reduce the length of the first arc of the longitudinal profile.
