    摘要： A method for checking the compliance of a checked optical characteristic of a checked ophthalmic lens (30) relative to an expected optical characteristic, from a non-deformed pattern (40) and a deformed pattern (20) each having a non-uniform contrast, the method includes the steps of: a) determining (A) an image pattern (50), which is the image of the deformed pattern through the checked ophthalmic lens, in predefined optical conditions, b) combining (B) the image pattern with the non-deformed pattern to form a test pattern (60), c) comparing (C) the test pattern with at least one reference pattern (70), and d) deducing (D) the compliance of the checked optical characteristic with the expected optical characteristic on the basis of the preceding comparison. A device for implementing such a checking method is also described.

    摘要： An optical article includes a substrate having a main surface coated with an antireflection coating and, directly contacting the antireflection coating, a precursor coating of an antifog coating obtained through the grafting on the antireflection coating of at least one compound B bearing a polyoxyalkylene group, the coating precursor of the antifog coating being coated with a surfactant film so as to form an antifog coating. The surfactant film contains at least one surfactant A having a sorbitan ring hydroxyl groups functionalized with OH-terminated polyoxyalkylene groups and R1 groups of formula:—(RdO)z—(Y)n2—R′, in which Rd is an alkylene group, z is an integer >1, Y is a divalent group, n2 is 0 or 1 and R′ is a saturated hydrocarbon group having 12 to 19, preferably 13 to 19 carbon atoms. Surfactants A provide a visual indication whether or not the antifogging effect will still be long-lasting.
