Neodymium Oxide Doped Headlight Lamps 2001-01-0319

Headlight glare is a continuing problem that has resisted efforts to solve it until now. A novel approach is provided in this paper by doping the glass with Neodymium Oxide, a rare earth compound, to filter out the excess yellow light. Neodymium Oxide doped lighting improves black and white contrast, so one can see road markings easier. The primary colors red, green and blue are enhanced with increased saturation, making them easier to see at low levels of illumination. Preliminary results indicate that “spots in your eyes” are reduced in intensity and in duration in the visual field. Apparent glare is reduced by a factor of 6 to 7 compared with standard lamps.
