How does Costa del Mar apply polarization to their sunglass lenses?

Costa del Mar Casts In

Polarizing a lens is the process of laminating on or casting in a polarizing film to a lens. Costa del Mar sunglasses use the cast-in process. The polarization film consists of polyvinyl alcohol molecules which run in horizontal parallel chains. These chains filter out light that bounces off horizontal reflective surfaces such as water, the highway, or the moisture in the air around you. Reflected light is 7 to 10 times brighter than ambient light and is commonly referred to as "glare."
