What is polarization?

Polarization is what happens when light waves from the sun are reflected off water, snow, the shiny surfaces of cars or boats etc. Even a wet road can be an issue. The reflected light creates intense glare that generates squinting, and makes it difficult to see. Polarized lenses in sunnies affectively reduces the glare eliminating the need to squint and allowing you to see clearly and comfortably without the harsh reflected light. Polarized film is created from rolls of polyvinyl acetate (PVA). Roughly speaking, this material has the consistency and thickness of plastic wrap. The process begins by heating and stretching PVA to five times its natural length, making it even thinner. This lengthens PVA?s long chain molecules, causing them to align. The stretched PVA is then dipped in iodine solution. The iodine is absorbed into the molecular chains forming long grids of parallel, darkened lines that are not visible to the human eye. The film is then dyed to the colour of the desired finished film. The darker the film, the more polarization it provides. Once the PVA is dyed and dried, it is delicate and hard to handle. To stabilize it, the film is mounted on a sheet of cellulose acetate butyrate (CAB). If it is going to be used in over-the-counter polarized lenses, it is placed between two sheets of CAB.
