Why are polarized sunglasses effective at reducing glare from horizontal surfaces like water or snow?
They absorb all light, making everything darker.
They reflect all incoming light away from the eyes.
They block the horizontally oscillating electric fields of reflected glare.
They change the wavelength of the light, making it less intense.
