A word on lightwaves and POLAR FLEX:   

Natural light is not polarized; its light rays diffused in space vibrate in all directions. If this light is reflected by flat surfaces, such as wet roads, snow, water, etc... it can be broken up into horizontal and vertical vibrations.  We then say that the polarized light has been reflected.  POLAR FLEX polarizing lenses are designed to selectively separate the useful light (vertical) from the white light (horizontal) and absorb the light rays reflected horizontally, thereby cancelling out dazzling reflections.   Dazzle, which is ten times brighter than ordinary light, distorts colours, changes the way we estimate depth, and impairs the quality of our vision.  So, POLAR FLEX polarizing lenses are especially designed for people who have problems with contrast, for people engaged in sports, for the elderly and car drivers off-road.  Particularly recommended for daytime driving, they help you relax and feel good, even if your eyes are sensitive.
