Abstract

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.
