Abstract: The invention relates to an optical article comprising a transparent substrate made of organic or inorganic glass, with main front and rear faces, at least one of said main faces comprising a multi-layer anti-reflection coating, wherein said anti-reflection coating comprises at least two visible-absorbing layers comprising a sub-stoichiometric titanium oxide, the visible-absorbing layers being such that the relative transmission factor of visible light Tv is reduced by at least 10% compared with the same article not comprising said visible-absorbing layers.

Abstract: The invention relates to an optical article comprising a transparent substrate which is made from organic or mineral glass and which has front and rear main faces, at least one of said faces being equipped with a multi-layer anti-reflective coating. The invention is characterised in that the anti-reflective coating consists of at least two layers which absorb in the visible region and which comprise a substoichiometric titanium oxide, said visible-absorbing layers being such that the visible light transmission factor Tv is reduced by more than 10% in relation to the same article without the visible-absorbing layers.
