摘要: 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.

摘要: Disclosed is a user wearable optical article including an optical substrate and an interferential coating. The interferential coating may be disposed the substrate and may be configured to selectively reflect light of at least one range of wavelengths of an incident light in the near infrared light spectrum. A peak reflectance measured at a substantially normal to the optical article may be at least 70%. An eyewear including an optical article and a method for producing an optical article are also disclosed. The method may include providing the optical substrate and providing the interferential coating disposed on the optical substrate. The interferential coating may selectively reflect light of at least one range of wavelengths of an incident light in the near infrared light spectrum. A peak reflectance may be at least 70% and the interferential coating has a mean reflectance of less than 1.5% in a visible light range.

摘要: This optical article has a back face on the side of a wearer's eye, a front face opposite to the back face and, on at least one of the front and back faces, an interferential multilayer coating comprising a stack of at least one layer of high refractive index material having a refractive index higher than 1.55 and at least one layer of low refractive index material having a refractive index of 1.55 or less, the refractive indexes being expressed for a wavelength of 550 nm. The optical article is designed in such a manner that it has high reflective properties for low incident angles when viewing the article from its front or back face and antireflective properties for high incident angles when viewing the article from its front or back face.

摘要: Disclosed is a method of manufacturing an ophthalmic lens to be mounted into a frame, including: a step of acquiring an optical prescription for the future wearer of the ophthalmic lens and an information relative to the ophthalmic lens and/or to the future wearer and/or to the frame; a step of calculating a surfacing instruction of the ophthalmic lens, the surfacing instruction being determined so that the ophthalmic lens once surfaced satisfies the optical prescription; and a step of surfacing during which the at least one optical face of the ophthalmic lens is surfaced according to the surfacing instruction. During the step of calculating, the surfacing instruction is calculated so that the optical face of the ophthalmic lens once surfaced includes a mark that results from the step of surfacing and that forms a code associated with the information.
