Abstract: This optical article comprises a base material having at least one face coated with an interferential multilayer coating providing either antireflective or high reflective properties. The coating comprises at least one layer of light absorbing material which has an adjustable composition and thickness, such that the visible light mean transmission factor of the coating is controllable to have a value between 95% and 5%.

Abstract: A spectacle ophthalmic lens mountable on a spectacle frame, the ophthalmic lens including: a fitting cross where the optical power is negative; a first zone extending in a temporal side of the fitting cross, wherein in the first zone when the ophthalmic lens is mounted on the spectacle frame, the optical power increases when a gazing direction moves towards the temporal side, and wherein over a nasal side of the fitting cross, the optical power of the ophthalmic lens is substantially same as at the fitting cross.

Abstract: An aspect of the disclosure relates to a method of determining an attitude of an eyewear. The method may include: detecting a light signal reflected from the eyewear with a digital device including a light sensor for a non-visible wavelength range; and calculating, using the light signal, an attitude of the eyewear. The attitude may be at least one of: a yaw angle, a pitch angle, a roll angle. A second aspect of the disclosure relates to an eyewear including at least a first lens. The first lens may include a first coating having reflection in the non-visible range of wavelengths. The first coating may further include a pattern with an orientation. A third aspect of the disclosure relates to a computer program product including instructions, which, when the program is executed by a digital device, causes the digital device to carry out the method.

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.
