Abstract: The present disclosure includes optical articles comprising a lens having first and second lens surfaces and a protective layer having first and second protective surfaces that is coupled to the lens such that the first protective surface is disposed on the second lens surface. The optical article can comprise a plurality of convex or concave optical elements defined on the second lens surface or the first protective surface. The protective layer can have a maximum thickness larger than a maximum height of each of the optical elements such that the protective layer encapsulates the optical elements.
