    Abstract: The present invention relates to an optical article having anti-reflection properties and high thermal resistance, comprising a substrate having at least one main face coated with a multi-layer anti-reflection coating comprising a stack of at least one high refractive index layer and at least one low refractive index layer, wherein the ratio: R T = sum ⁢⁢ of ⁢⁢ the ⁢⁢ physical ⁢⁢ thicknesses ⁢⁢ of ⁢⁢ the low ⁢⁢ refractive ⁢⁢ index ⁢⁢ layers ⁢⁢ of ⁢⁢ the ⁢ anti ⁢ - ⁢ reflection ⁢⁢ coating sum ⁢⁢ of ⁢⁢ the ⁢⁢ physical ⁢⁢ thicknesses ⁢⁢ of ⁢⁢ the high ⁢⁢ refractive ⁢⁢ index ⁢⁢ layers ⁢⁢ of ⁢⁢ the ⁢ anti ⁢ - ⁢ reflection ⁢⁢ coating is higher than 2.1. If the anti-reflection stack comprises at least one low refractive index layer having a physical thickness ≧100 nm which is not the outermost layer of the anti-reflection coating, said relatively thick layer and the underlying layers are not taken into account in RT calculation.

    Abstract: The invention concerns a method for making an antiglare stack by vacuum evaporation on an organic substrate (1) at a temperature lower than 150 DEG C, comprising steps which consist in depositing at least a layer of material having a refractive index different from that of MgF2 (4, 4'), preparing the surface of the thus coated substrate, and depositing an outer MgF2 layer (5) without ionic assistance. The resulting antiglare stack on organic substrate exhibits good adherence and good scratch resistance. The invention is applicable to ophthalmic lenses.
