POLARIZING FACTS

There are two kinds of people in this world — those who wear sunglasses and those who wear sunglasses with polarized lenses. Pilots, professional drivers, boaters, skiers, bikers and golfers — you already know what’s up. For activities that call for the elimination of sun glare for optimum safety and performance, polarized sunglasses are essential.

HOW IT’S MADE

The lens is made by melting plastic and pouring into a mold with the polarizing film. The plastic hardens around the film, fusing together to create one material. For polycarbonate lenses, the polarizing film is applied to the front of the lens then a petroleum-based scratch-resistant coating is applied on top of it. Polarized polycarbonate spectacles are the thinnest and lightest polarized options in the eyewear market.

BUT HOW DO POLARIZED LENSES WORK?

There are three types of light — direct, reflected and ambient — that scatter, bounce and refract off of surfaces. When light travels in a constant direction off of a reflected surface — like the road, snow or water — it travels to our eyes on a horizontal plane, causing glare and reducing visibility. Polarized lenses not only eliminate harmful ultraviolet rays, but they filter light vertically, presenting incomparable clarity and depth.
