Abstract: 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.

Abstract: This computer-implemented method for providing an automated prediction of a change of a state of fatigue of a subject carrying out a visual task involving any kind of visual content comprises: providing a plurality of input data, relating to the subject, to a fatigue state change predictive model, wherein the plurality of input data comprises at least one subjective measurement relating to the subject and/or at least one objective measurement relating to the subject and/or at least one other subject-related datum; obtaining, by a processor implementing the model, a value representing a level of change of the state of fatigue of the subject.
