The Iodine crystals in the polarized film are aligned in parallel rows like a venetian blind to block light one direction. This is why you cannot have a clear polarizer. If the crystals were clear, they could not do their job blocking light in a specific direction.
Re: does anyone make a clear polarized eyeglass lens?
I think most of polarized has colors, the difference is light or heavy?
Our factory offer some good quality polarized with very little blue color, but it can not be clear as water.
