1. An optical article comprising:
a film layer having opposing first and second film surfaces, wherein the film layer is embossed such that:
the second film surface defines a plurality of convex optical elements;
the first film surface defines a plurality of concave optical elements; and
each of the convex and concave optical elements has a diameter that is less than or equal to 2.0 millimeters (mm) and a maximum height, measured in a direction perpendicular to the first film surface, that is less than or equal to 0.1 mm; and
a primary optical layer that has opposing first and second primary optical surfaces and is coupled to the film, wherein:
the second primary optical surface is disposed on the second film surface and the primary optical layer has a maximum thickness, measured in a direction perpendicular to the second film surface between the first and second primary optical surfaces, that is larger than the maximum height of each of the convex optical elements such that the convex optical elements are encapsulated within a volume defined between the first film surface and the first primary optical surface;
wherein the optical article is adapted to correct refractive errors of an eye.
