    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 antiglare film includes a substrate having a sheet-like shape, a lower hard coat layer disposed overlapping the substrate, and an upper hard coat layer disposed layered on a side of the lower hard coat layer opposite to a side of the substrate. A thickness of the lower hard coat layer is a value within a range of at least 150% or more of a thickness of the upper hard coat layer.
