Abstract
Beams of light can be controlled by polarization, by rotating polaroid filters to focus or block out light. Cross polarizer filters can eliminate car headlight glare at night, and reduce reflection on camera lenses, microscopes, compasses for polar navigation, and the brightness of white paper. Sunglasses also use polaroid lenses that aid drivers by cutting down on pavement glare.
