An anti-reflective coating system configured to resist crazing resulting from applied compressive forces, and an optical article employing the anti-reflective coating system; and methods of forming the same. The methods include forming a first anti-reflective coating over a first surface of the optical article and applying a second anti-reflective coating over a second surface of the optical article, where the second anti-reflective coating has substantially the same reflectance than the first anti-reflective coating and a mechanical property distinct from the first anti-reflective coating.
