Optical article to provide vision correction for devices using eye tracking device

Abstract

The invention relates to an optical article comprising a transparent substrate with a front main face and with a rear main face, at least one of the main faces being coated with a multilayered interferential coating comprising a stack of at least one high refractive index layer (HI) having a refractive index higher than or equal to 1.55 and at least one low refractive index layer (LI) having a refractive index layer lower than 1.55, wherein said multilayered interferential coating has: ▪ mean light reflection factor in the visible region, noted R v, that is lower than or equal to 2.5% for at least an angle of incidence lower than or equal to 35°; ▪ a mean reflection factor for wavelengths ranging from 800 nm to 900 nm, noted R m(800900), that is lower than or equal to 1.5% at an angle of incidence lower than or equal to 20°, characterized in that: ⋅ ▪ said multilayered interferential coating has a mean reflection in the near infrared (NIR) region ranging from 900 nm to 2000 nm, noted R, that is higher than or equal to 11.5% at an angle of incidence lower than or equal to 20° and/or said transparent substrate comprises at least one absorbing dye which absorbs in the near infrared region at a wavelength ranging from 900 to 2000 nm.
