What Are Polarized Sunglasses?

Perfect for hiking, camping, or your work commute, polarized sunglasses are regular sunglasses whose lenses have been coated with a polarized chemical filter. I realize that doesn’t explain so much, so let’s dive into the process of polarization and how it affects what you see when you gaze through a pair.

Most light waves, be they from the sun or even light bulbs, vibrate and simply radiate out in all directions. As soon as a group of light waves becomes aligned to a single direction, that light is considered polarized.

Polarization is possible by both natural and artificial sources of light and can occur both naturally and/or artificially. For example, the glare that you see when you look across a body of water or when the sun is reflected off of the horizontal hood of a car, that light is polarized.

How Do Polarized Lenses Work?

The polarized filter is made of molecules that naturally line parallel to each other and, when applied consistently to a lens, creates a microscopic filter than absorbs any light matching their alignment. Most of the annoying glares that make us want to wear polarized lenses occur from horizontal surfaces, thus the polarized filter applied to lenses are aligned vertically to block horizontally polarized light and to allow vertically polarized light to pass through in turn reducing the amount of glare that comes from horizontally polarized light.
