Abstract
A vehicle window includes a first window side and a second window side. The first window side includes an optical center and a plurality of grooves positioned about the optical center. The grooves have a number of dimensions including a depth and a width. The grooves define surfaces effective to redirect light that passes through said window. At least one dimension of the grooves is varied about the optical center. The window is effective to provide a plurality of angles of light redirection about the optical center.
