Abstract: Disclosed is an optical article including a substrate having a front main face and a rear main face, the rear main face being coated with a multilayer antireflection coating. The outermost layer of the multilayer antireflection coating is a layer A containing silicon, carbon and fluorine atoms, the layer A having a refractive index lower than or equal to 1.45 and a thickness higher than or equal to 20 nm. The mean light reflection factor Rv on the rear main face between 380 nm and 780 nm is lower than or equal to 1.5%. The mean reflection factor Ruv on the rear main face between 280 nm and 380 nm, weighted by the function W (2) defined in the ISO 13666:1998 standard, is lower than or equal to 7%, for an angle of incidence of 35°.

Abstract: An optical article includes a substrate with front and rear main faces, one main face coated with a columnar micro- or nano-structured coating. The substrate and optical article are transparent in at least a part of the visible region ranging from 380 to 780 nm, along at least one incidence angle. The columnar micro- or nano-structured coating includes an array of columns including each a core and an upper layer covering the core, the core and the upper layer being structurally and/or chemically different and have light absorbing properties with an extinction coefficient “k” ≥10-2 in the spectrum 250-2500 nm and are able to cause a change in transmission or in reflection of incident light through the optical article as a function of the angle of incidence of light. Also disclosed is a method for manufacturing an optical article including a columnar micro- or nano-structured coating.

Abstract: An ophthalmic tinted glass (10) comprises a substrate-forming base eyeglass (1), a first layered structure (2) which covers a convex face (Cx) of the base eyeglass, and optionally a second layered structure (3) which covers a concave face (Cc) of the base eyeglass. The first layered structure has a function of selective reflection increase, and the second layered structure is antireflective. Such ophthalmic tinted glass produces solar protection while having a mean transmittance value in a wavelength range from 460 nm to 10 nm, or 465 nm to 495 nm, which is high enough for avoiding biological, hormonal and behavioural disorders for a wearer of the tinted glass.
