Optical substrates are coated with blooming layers. The substrate is placed into a vacuum vessel, the vessel is evacuated and the substrate is subjected to infrared radiation before and during the evaporation process. The substrate can be a plastic material and is preferably polydiethylene-glycol-diallyl-carbonate. Preferably initially a thin layer of high-refractive index silicon monoxide and then a second thicker, lower-refractive index silica are deposited. The resulting optical articles such as eye-glasses and watch glasses have excellent properties.
