Optical films, optical stacks including the optical films, and display systems including the optical films are described. The optical film includes a first major surface that may include a plurality of first microstructures that extend along a first direction. The optical film also includes a second major surface that is opposite to the first major surface and includes a plurality of second microstructures. The second major surface has an optical haze that is not greater than about 3% and an optical clarity that is not greater than about 85%.

Light redirecting film is disclosed. The light redirecting film includes a first major surface that includes a plurality of first microstructures that extend along a first direction. The light redirecting film also includes a second major surface that is opposite to the first major surface and includes a plurality of second microstructures. The second major surface has an optical haze that is not greater than about 3% and an optical clarity that is not greater than about 85%. The light redirecting film has an average effective transmission that is not less than about 1.75.
