    • 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.
    • 一种光学制品的制造方法,其特征在于:使基于有机聚合物获得有机基材,所述有机聚合物的吸水度大于或等于0.6重量%,相对于所述基材的总重量, 吸水量等于干燥后材料吸收的水的重量,然后在相对湿度100%和大气压下在50℃的室中储存800小时; 通过在大于或等于90℃的温度下加热基底至少20分钟的时间,在基底上形成硬的耐磨涂层; 将被硬质耐磨涂层覆盖的基材暴露于潮湿气氛中,以使在阶段中蒸发的水回收到有机基材; 并通过真空蒸发沉积不透水的无机涂层。
