1. An article comprising:

  • a substrate having a substrate surface; and

    an anti-reflection coating disposed on the substrate surface forming a coated surface, wherein the coated surface exhibits a first average reflectance when the coated surface is in a pristine condition, and a second average reflectance after removal of a surface thickness of about 20 nm to about 500 nm of the anti-reflection coating from the coated surface that provides a contrast ratio (the second average reflectance;

    the first average reflectance) in the range from about 0.5 to about 50, over the visible spectrum, wherein the anti-reflection coating has a thickness that is greater than the surface thickness and wherein the reflectance is measured under a CIE illuminant.
