Abstract: Articles are described that may include substrates having a major surface, the major surface comprising a first portion and a second portion. A first direction that is normal to the first portion of the major surface may not be equal to a second direction that is normal to the second portion of the major surface. The angle between the first direction and the second direction may be at least 15 degrees. An optical coating may be disposed on at least the first portion and the second portion of the major surface. The optical coating may form an antireflective surface.

Abstract: Methods for coating a glass-based article, for example a cover glass, with a coating layer that is not deposited on the perimeter edge of the glass-based article. The methods may include disposing a mask having an eave over a glass-based article to protect perimeter portions of the glass-based article from coating of the coating layer during a deposition process. The eave may be dimensioned to form a coating layer having non-uniform coating thickness region around the edge of the coating layer that is not visible to the naked eye on the surface of a glass-based article. The methods may be used to make a glass-based article with non-edge-to-edge coating layers.
