摘要： An optical article includes a front face adapted to receive incident optical beams and a back face through which transmitted optical beams exit to reach an eye, wherein the front face includes an interferential multilayer coating including a stack of dielectric layers. The interferential multilayer coating provides the optical article with a mean visible light reflection factor Rv that is lower than or equal to 2.0% over a range of angle of incidence included between 0 and 20 degrees, and that is higher than or equal to 2.0% over a range of angle of incidence included between 40 degrees and 60 degrees, the optical article having a higher mean visible light transmittance for low incidence angles and a lower mean visible light transmittance for high incidence angles.
