Abstract: Process for manufacturing of an optical article which comprises: making available an organic substrate based on an organic polymer having a degree of water uptake of greater than or equal to 0.6% by weight, with respect to the total weight of the substrate, the degree of water uptake being equal to the weight of water absorbed by the material after drying and then storing for 800 hours in a chamber at 50° C. under a relative humidity of 100% and at atmospheric pressure; forming a hard abrasion-resistant coating on the substrate by heating the substrate at a temperature of greater than or equal to 90° C. for a period of time of at least 20 minutes; exposing the substrate covered with the hard abrasion-resistant coating to a humid atmosphere, so as to restore, to the organic substrate, the water evaporated during stage; and depositing of a water-impermeable inorganic coating by vacuum evaporation.
