A plurality of microstructures is provided, with each microstructure having at least a first side and at least a second side terminating at a peak. At least some of the peaks can include an elevated portion to space the peaks away from adjacent optical sheets, surfaces, films, substrates, or other layers to minimize wet-out, Newton's rings, abrasions, moire fringes, or other undesirable optical conditions. In other embodiments, an optical film is also provided that includes a first plurality of microstructures having a base, a first side, and a second side, and a second plurality of microstructures having a base, a first side, and a second side, the first side including a first planar surface, and the second side including a second planar surface and a third planar surface.
