    摘要: A process for manufacturing an ophthalmic lens having at least one optical function, includes the following steps: additively manufacturing (100) an intermediate optical element by depositing a plurality of preset volume elements of at least one material having a preset refractive index, the intermediate optical element including a target ophthalmic lens and a thickness allowance consisting of a portion of the plurality of volume elements; and subtractively manufacturing (300), by machining, the target ophthalmic lens from the intermediate optical element, the machining being carried out in a preset sequence, of at least one step, the preset sequence making it possible to subtract the thickness allowance, the additive manufacturing step (100) including a step of determining a manufacturing setpoint for the intermediate optical element in which the thickness allowance is determined depending on the preset sequence defined in the subtractive manufacturing step (300).

    摘要: A method for manufacturing an ophthalmic lens (40) having at least one optical function, includes the step of additively manufacturing (118) a complementary optical element (12) by depositing a plurality of predetermined volume elements (24) of a material having a predetermined refraction index on a predetermined manufacturing substrate (10), the complementary optical element being configured such as to be assembled with an initial optical system (30), the manufacturing step including the step of determining a manufacturing setting (116) from properties relating to the deformation of the complementary optical element, which deformation is caused by transferring the latter onto the initial optical system, and the step of determining a setting including the step of determining the deformation properties (113) of the complementary optical element from geometric properties of the manufacturing substrate and the initial optical system and from properties of the optical function to be provided to the ophthalmic lens.

    摘要: A method for checking the compliance of a checked optical characteristic of a checked ophthalmic lens (30) relative to an expected optical characteristic, from a non-deformed pattern (40) and a deformed pattern (20) each having a non-uniform contrast, the method includes the steps of: a) determining (A) an image pattern (50), which is the image of the deformed pattern through the checked ophthalmic lens, in predefined optical conditions, b) combining (B) the image pattern with the non-deformed pattern to form a test pattern (60), c) comparing (C) the test pattern with at least one reference pattern (70), and d) deducing (D) the compliance of the checked optical characteristic with the expected optical characteristic on the basis of the preceding comparison. A device for implementing such a checking method is also described.
