Abstract
A vehicle visor includes a visor body for attachment to a vehicle, a mirror and a light source mounted to the body, and a lens attached to the body for controlling the distribution of light from the light source. The lens includes a surface with microvariations formed therein to define a holographic optical element that directs the light into a predetermined pattern for illuminating the face of the user. The lens so formed eliminates undesirable uneven light distribution such as 'spider webbing,' light/dark patchiness and chromatic aberrations in and around the predetermined light pattern.
