The Light From The Sun Naturally Becomes Partially Polarized Due To Reflecting Off Electrons In Air Molecules, Causing The Light To Scatter Into What Appears As Haze. A Polarizing Filter Arranges And Filters This Directionally Polarized Light Perpendicularly To The Reflected Light, Allowing For The Absorption Of Much Of This Light. This Results In A Noticeable Reduction Of Glare And Reflections From Non-Metallic Surfaces And An Increase In The Saturation Of Skies And Foliage.
