Utility
Progressive multifocal lens having an enlarged intermediate distance vision region
28 Oct 19
A progressive multifocal lens adapted to correct a user's vision and including a first major surface and a second major surface, wherein the first major surface is positioned closest to the user's eye when the progressive multifocal lens is worn by the user, the progressive multifocal lens including: a far-distance vision region having a first refractive power, a near-distance vision region having a second refractive power, an intermediate-distance vision region having a third refractive power, and a first and a second progressive region, a main line of sight extending from the far-distance vision region to the near-distance vision and passing through the intermediate-distance vision region.

Utility
Method for manufacturing an ophthalmic lens comprising a marking step for producing permanent technical marks on said ophthalmic lens
28 Oct 19
A method for manufacturing an ophthalmic lens (12), includes a marking step for producing permanent technical marks (24) on the lens, which includes a body (29), a first surface (20) and a second surface (28) opposite the first surface (20); the step of additive manufacturing (110-112) of the body and the first and second surfaces, by depositing a plurality of first predetermined volume elements of a first material having a first complex index of refraction (35), in order to obtain first and second optical surfaces, respectively, of the first and second surfaces; and the step of additive manufacturing (113) of the marks by depositing, during the deposition of a plurality of the first volume elements of the first material, at least one second predetermined volume element of a second material having a second complex index of refraction (30) other than the first complex index of refraction of the first material.

Utility
Method and system for producing an ophthalmic lens
14 Oct 19
A method for producing an ophthalmic lens, comprising an additive manufacturing step (100) for producing an intermediate optical element by depositing a plurality of elements of predefined volume of at least one material, said element comprising a target ophthalmic lens supplemented with at least one overthickness, and a flexible polishing manufacturing step (300) for producing said lens from said element by at least partially subtracting the overthickness so as to filter irregularities formed on said element during said additive manufacturing step; said additive manufacturing step comprising a step of defining a manufacturing setpoint for said element in which said overthickness is defined on the basis of predefined parameters of said flexible polishing step, i.e., a geometric characteristic representative of a spatial cutoff frequency and a geometric characteristic representative of a material removal capacity.
