Abstract: A vehicle light assembly includes a housing for attachment to a vehicle, a light source mounted to the housing, and a lens and/or reflector attached to the housing for controlling the distribution of light from the light source. The lens and/or reflector includes a surface with microvariations formed therein to define a holographic optical element that directs the light into a predetermined pattern for illuminating an area. The lens so formed simultaneously eliminates undesirable uneven light distribution such as glare, "spider webbing," light/dark patchiness and chromatic aberrations in and around the predetermined light pattern.

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.
