Polarized glasses provide another way to protect your eyes. Asphalt road reflected light is more special polarized light. The difference between this reflected light and the light from the sun or any artificial light source is the order problem. The polarized light is formed by waves that vibrate in one direction, and the general light is formed by waves of unsteady vibrations, which are like a group of unarmed people walking around with a group of marching march , Formed a clear to the scriptures. In general, the reflected light is an orderly light. Polarized lenses are particularly effective in blocking such light because its filterability is effective. This lens only to a certain direction of the vibration of vibration through, as the light "comb" the same. For road reflex problems, the use of polarized glasses can reduce the transmission of light, because it does not allow parallel vibration with the road through the light. In fact, the long molecules of the filter layer are directed in the horizontal direction and can absorb the horizontal polarized light. In this way, most of the reflected light is eliminated, and the surrounding environment of the entire illumination did not decrease.
