The present invention relates to a method for producing a photochromic oxy-hydride material as well as a photochromic component. The method comprising the steps of: —first the formation on a substrate of a layer of an essentially oxygen free rare earth metal hydride with a predetermined thickness using a physical vapor deposition process; and—second exposing the metal hydride layer to oxygen where the oxygen reacts with the metal hydride, said second step being performed in an environment having a water content defined by a water amount in air at sea level pressure with RH between >0% and 100% RH for temperatures between 0° C. and 40° C., preferably 25° Celsius.
