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

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 two high refractive index layer (HI) having a refractive index higher than or equal to 1.55 and at least two low refractive index layer (LI) having a refractive index layer lower than 1.55, wherein said multilayered interferential coating has:

• a mean light reflection factor in the visible region, noted Rv, 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 RmET(800-900), that is lower than or equal to 1.5% at an angle of incidence lower than or equal to 20°;
• a mean reflection factor in the near infrared (NIR) region ranging from 900 nm to 2000 nm, noted RmMIR, 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;
• an average transmission factor for wavelengths ranging from 800 nm to 900 nm, noted TmET(800-900), that is higher than or equal to 60% at an angle of incidence lower than or equal to 20°;
• and
• an average transmission factor for wavelengths ranging from 900 nm to 1500 nm, noted Tm(900-1500), that is lower than or equal to 80% at an angle of incidence lower than or equal to 20°.
