Recent Research on Neodymium Glass as Applied to Headlights, Rear View Mirrors, and Windshields 2005-01-0440

Neodymium Oxide, as a component of glass, selectively filters out a portion of the yellow light. Neodymium Oxide can be incorporated into the glass of the headlight lamp, the rear view mirror, and the windshield of a motor vehicle. A series of tests was conducted with 30 subjects recruited to quantify the reduction in glare and improvement in vision by the use of Neodymium Oxide doped glass for these applications. Subjects were put through a series of tests in an optometric examination room setting. The group was then divided in half, and one half received new standard headlights, and the other half received Neodymium headlights in a road test.
