What is polarization?
The glare of the sun on the snow (and other surfaces) is highly polarized! Polarized lenses are used in sunglasses to reduce glare from reflective surfaces such as the surface of a road or the hood of a car. They accomplish this feat through a process called polarization, much like a venetian blind controls sunlight through a window.
Sunlight itself is not polarized - light from the sun will either be absorbed or reflected horizontally, diagonally or vertically. The problem this causes for people lies in the horizontal reflectivity. Sunlight bouncing off a horizontal surface will strike the viewer's eyes at a similar angle. This means the glare from the surface of the road or the car hood will be strong. Polarized lenses have a laminated surface containing vertical stripes. These stripes only allow vertically-polarized light to enter the wearer's eyes. Glare is eliminated because the horizontally-polarized light waves cannot bypass the polarized filter
Now let’s get ready for the season!
