Polarization and Eyes
See also: Polarization (waves)Visible light waves from the sun travel in all directions. When this scattered light meets a horizontal surface, like a road or water, a large portion of the light is reflected with horizontal polarization. This horizontally-polarized light is seen as white glare, and masks light that is useful to the human eye, reducing visibility. By using a sheet of vertical polarizing material, the horizontally-polarized component can be significantly attenuated, reducing the overall light level reaching the eye. This improves contrast, and thus perception of the scene.

Famous quotes containing the word eyes:
“You call yourself free? I want to hear your ruling thought and not that you have escaped a yoke. Are you such a one as was permitted to escape a yoke? There are some who threw away their ultimate worth when they threw away their servitude. Free from what? What is that to Zarathustra! But your eyes should announce to me brightly: free for what?”
—Friedrich Nietzsche (1844–1900)
