Abstract: An optical construction includes a lens film having a plurality of optically transparent first beads at least partially embedded in a first layer. A light blocking second layer is disposed on the lens film and defines a plurality of through openings therein extending at least partially between opposite major top and bottom surfaces of the second layer. The through openings are aligned to the first beads in a one-to-one correspondence.
