Abstract: A spectacle lens includes a substrate and an anti-reflection or mirror interference coating covering the substrate on the side of the front face, the interference coating forming a one-dimensional or two-dimensional bar code pattern, the marking being formed by a plurality of point holes on a portion of a thickness of the interference coating, the front face having, away from the point holes, a coefficient of reflection of light having a predetermined nominal value and, in each the point hole, a coefficient of reflection of light having a particular predetermined value that is different from the nominal value.
