1. A mold with an optical surface having an anti-reflective coating that is transferable to an optical surface of a lens, comprising:

  • (a) a deposition layer of a fluoride or oxide material deposited to the optical surface;

    (b) a layer of a hydrophobic material over the deposition layer wherein the hydrophobic material consists essentially of a super hydrophobic material and a dipodal silane;

    (c) a first layer of SiO2 that is deposited without using ion assist and with a thickness of about 5 to 40 nm deposited to the layer of hydrophobic material;

    (d) an anti-reflective coating layered structure deposited to the first layer of SiO2;

    (e) a layer of a silane coupling agent that is deposited using vapor deposition and with a monolayer thickness deposited over the anti-reflective coating layered structure or by dip coating using a solution of silane coupling agent in an aprotic solvent, and(f) a scratch resistant hard coating,wherein the dipodal silane is different from the super hydrophobic material, and an amount of the dipodal silane is effective to prevent the anti-reflective coating layered structure from crazing.
