What are Polarized Reading Sunglasses?

The light dispersed by the sun spreads in all directions. When it hits flat surfaces the light that is reflected off the surface tends to become polarized. Reflecting light beams travel in a strict horizontal direction. This direction of light creates an intense brightness that causes glare and reduces visibility.  Polarized bifocal sunglass lenses have an exceptional filter that blocks reflected light while providing 100% UV protection allowing you to read comfortably outdoors.
