Abstract: Implementations described and claimed herein provide systems and methods for adding a chosen functional coating on an optical surface of a spectacle lens. In one implementation, it is determined if identified features of the optical surface of the spectacle lens are compatible with the chosen functional coating according to a first set of rules. The features of the optical surface are identified based on an analysis of a quality of the optical surface. Manufacturing information for the chosen functional coating is generated based on the determined compatibility. The manufacturing information includes information for depositing the chosen functional coating on the optical surface where the identified features are compatible with the chosen functional coating and on a modified optical surface where the identified features are not compatible with the chosen functional coating.
