Coated articles with optical coatings having residual compressive stress

A coated article comprising:

• a substrate comprising a major surface;
• an optical coating disposed on the major surface of the substrate and forming an air-side surface, the optical coating comprising one or more layers of deposited material;
• wherein:
• at least a portion of the optical coating comprises a residual compressive stress of more than about 50 MPa;
• the optical coating comprises a strain-to-failure of about 0.4% or more as measured by a Ring-on-Ring Tensile Testing Procedure;
• the optical coating comprises a maximum hardness of 12 GPa or more as measured on the air-side surface by a Berkovich Indenter Hardness Test along an indentation depth of about 50 nm and greater;
• and
• the coated article comprises an average photopic transmission of about 80% or greater.
