| description | The invention relates to an optical article having antireflection properties, optionally antistatic properties, having a high thermal and abrasion resistance, as well as the method for producing the same. The article of the invention comprises a substrate and, starting from the substrate: a sub-layer comprising a SiO2-based layer, said SiO2-based layer having a thickness greater than or equal to 75 nm et free from Al2O3; and a multilayered antireflection coating comprising a stack consisting in at least one high refractive index layer and at least one low refractive index layer, all the low refractive index layers of which comprising a mixture of SiO2 and Al2O3, and the high refractive index layers of which are not layers that do absorb in the visible region comprising a substoichiometric titanium oxide and reducing the relative visible light transmission factor (Tv) of the optical article by at least 10% as compared to a same article without any of said visible light absorbing layers. |
