摘要： Disclosed are a method and device for manufacturing an ophthalmic lens for eyeglasses intended to be placed in front of an eye of a wearer, the ophthalmic lens having a desired optical function including a dioptric function adapted to a prescription of the wearer. The method includes: providing an optical element made of a first material having a first refractive index, the optical element being intended to be modified to manufacture the ophthalmic lens; providing data relative to the modification of the optical element enabling to obtain the desired optical function; determining at least one zone in the first material based on data; and modifying the refractive index of the first material to form a pattern in the determined zone with focused femtosecond laser pulses according to data so as to obtain an ophthalmic lens having the desired optical function.

摘要： Disclosed is a method for determining an updated visual correction need for designing a new vision correcting device of an individual already having a previous vision correcting device previously designed to correct his/her vision, wherein, in a first step, a previous level of correction of the previous vision correcting device is acquired, in a second step, a current vision acuity parameter of the individual wearing the previous vision correcting device is assessed, and, in a third step, the updated visual correction need is determined based on the previous level of correction of the previous vision correcting device acquired in the first step and on the current vision acuity parameter assessed in the second step. A complementary visual correction need can also be determined.

摘要： Disclosed is a method for marking an optical article coated with an interference coating including at least two layers, an inner layer and an outer layer, and having reflection coefficient Re; by exposure of the inner layer, at a marking point, by way of a laser beam at a marking wavelength, in such a way as to ablate the inner layer and any layer further away from the substrate; the ablated area having a reflection coefficient Rm different from Re by at least 1%; the inner layer absorbing the marking wavelength to a greater degree than any layer further away from the substrate. Also disclosed is an optical article coated with an interference coating having at least two layers, an inner layer and an outer layer, the article including a marking pattern formed by local absence of layers.

摘要： A spectacle lens includes a substrate and an anti-reflection or mirror interference coating covering the substrate on the side of the front face, the interference coating forming a one-dimensional or two-dimensional bar code pattern, the marking being formed by a plurality of point holes on a portion of a thickness of the interference coating, the front face having, away from the point holes, a coefficient of reflection of light having a predetermined nominal value and, in each the point hole, a coefficient of reflection of light having a particular predetermined value that is different from the nominal value.
