Color-Corrected Motor Vehicle Headlight, Rearview Mirror, and Windshield for Glare Control

This report documents the work done in a Safety Innovations Deserving Exploratory Analysis (IDEA) research project on the visual effectiveness of Neodymium Oxide doped headlights, rear view mirrors, and windshields in reducing glare and improving vision. This research project had two stages: clinical optometric experimentation under controlled conditions, and a subjective road test. Several tests showed a significant improvement in visual performance in favor of the Neodymium Oxide doped glass used in the headlight, rear view mirror, and windshield. All three applications of Neodymium Oxide doped glass to the motor vehicle industry are sufficiently advanced in product development for potential implementation. Presently, Neodymium Oxide doped headlights are being sold in the aftermarket by the Federal Mogul Corporation. Neodymium Oxide doped flat glass can be made in sufficient quantity for use in rear view mirrors and in windshield glass. There are no known technological hurdles for their immediate implementation.
