A spectacle lens includes at least one substrate and at least one photochromic layer. The spectacle lens exhibits no swelling of the coating and/or of the substrate in the event of at least one damage to the surface of the spectacle lens with a force of ≤65 m N after contamination of the surface of the spectacle lens with at least one organic acid over a period from a range of 12 hours to 84 hours. Further, a method for producing the spectacle lens and the use of at least one chemically modified layer and/or at least one barrier layer for coating a spectacle lens substrate is disclosed.

An optical element has a substrate body made from transparent plastic and a coating having multiple layers. The coating includes a hard lacquer layer adjoining the substrate. The coating has a diffusivity ensuring the absorption of water molecules passing through the coating in the substrate and the release of water molecules from the substrate through the coating from an air atmosphere on that side of the coating facing away from the substrate with a flow density which, proceeding from the equilibrium state of the quantity of water molecules absorbed in the substrate in an air atmosphere at 23&#xb0; C. and 50% relative humidity, brings the setting of the equilibrium state of the quantity of water molecules absorbed in the substrate in an air atmosphere at 40&#xb0; C. and 95% relative humidity within an interval not more than 10 h longer than for setting this equilibrium under corresponding conditions with an identical uncoated substrate.
