Abstract
A sun guard for a vehicle may be constructed with a darkly tinted transparent acrylic shield to enable a vehicle occupant to comfortably view objects such as a traffic light even while the sun is within nearly the same line of vision, eliminating blinding glare by inhibiting the direct transmission of sunlight to a substantially uniform average of about two to three percent across the visible spectrum. A lighter tinted shield may alternatively be provided with a dark window film covering a major surface of the shield to provide similar visible light transmission characteristics. A clip having at least one double clamp spring pivotally attaches the sun guard to an existing opaque sun visor.
