Abstract: A system including a sensor configured so that the presence of a spectacle within a detection range of the sensor is detectable by the sensor when the spectacle includes a predetermined identification structure. The system may further include a control unit configured to receive an information from the sensor and to carry out a predetermined action, upon a condition in which the one or more spectacle lenses may be detected. A method may include detecting the presence of the spectacle within a detection range, and further providing, by the sensor, an information to the control unit. The information may confirm the detection of the spectacle. The method may include carrying out, by the control unit, the predetermined action. A computer program product including instructions to cause the system to execute the steps of the method. A computing device including the sensor and a memory.

Abstract: The invention relates to an optical lens comprising a substrate having a front main face and a rear main face, at least one main face of which being successively coated with a first high refractive index sheet which does not comprise any Ta2O5 layer, a second low refractive index sheet a third high refractive index sheet, a monolayer sub-layer having a thickness higher than or equal 0 to 100 nm, and a multilayer interferential coating comprising a stack of at least one high refractive index layer and at least one low refractive index layer. The mean reflection factor RUV on said rear main face between 280 nm and 380 nm, weighted by the function W(λ) defined in the ISO 13666:1998 standard, is lower than 10%, for an angle of incidence of 35° .20

Abstract: Disclosed is a computer-implemented method for designing an interferential stack of an antireflective coating for an optical component to minimize the deviation in the optical performance when associated with different substrates, the method including the steps of: determining for a plurality of configurations a deviation of the optical performance between a plurality of substrates depending on values of a same configuration determined for each substrate, a deviation of the optical performance being determined for each optical property; and selecting a configuration of the interferential stack having at least one minimized deviation of the optical performance.
