The term polarization or polarized is derived from the manufacturing process of these lenses.
Polarized lenses are actually two lenses laminated together at opposite poles with a tinted film between the two surfaces.
Today, polarized lenses are available in many different colors and densities. The three most popular colors are; gray, brown and gray-green (G-15). Polarized lenses are also available in lighter tints and gradients. However, the effectiveness of the polarization is diminished in lighter colors.
Recently, Essilor and Transitions has developed a variable polarization lens that changes from light to dark called Transitions Vantage. The lens has had limited success since polarization is only effective when the lens gets dark and does not work behind the windshield of a vehicle. www.mauijim.com
