Optical bodies are disclosed that include an optical film and at least one rough strippable skin layer operatively connected to a surface of the optical film. The at least one rough strippable skin layer can include a continuous phase and a disperse phase. Alternatively, the at least one rough strippable skin layer can include a first polymer, a second polymer different from the first polymer and an additional material that is substantially immiscible in at least one of the first and second polymers. In some exemplary embodiments, a surface of the at least one rough strippable skin layer adjacent to the optical film comprises a plurality of protrusions and the adjacent surface of the optical film comprises a plurality of asymmetric depressions substantially corresponding to said plurality of protrusions. In addition, optical bodies are disclosed that include an optical film having a surface with asymmetric depressions, the asymmetric depressions having a major dimension substantially collinear with a major ax
