Abstract (en)
[origin: WO2009106765A1] The invention relates to a method for preparing an ophthalmic lens for mounting the same into the rim of a spectacles frame that comprises the step of acquiring a first longitudinal profile of said rim and an orientation parameter of said first longitudinal profile relative to a horizontal or vertical line of said rim, and the step of trimming the ophthalmic lens in order to form a substantially profiled fitting rib having a desired section and extending along a second longitudinal profile (25) derived from the first longitudinal profile and having an orientation derived from said orientation parameter. According to the invention, the method comprises the step of determining at least one singular portion (Z1-Z12) of the second longitudinal profile on the basis of said orientation parameter. During the trimming step, the fitting rib is locally cropped in said singular portion.
