Disclosed herein are coated articles which may include a substrate and an optical coating that includes one or more layers of deposited material. At least a portion of the optical coating may include a residual compressive stress of more than 100 MPa. The coated article may include a strain-to-failure of 0.4% or more as measured by a Ring-on-Ring Tensile Testing Procedure. The optical coating may include a maximum hardness of 8 GPa or more and an average photopic transmission of 50% or greater.
