I recently went out and bought myself a pair of new sunglasses for the summer. I was sure to get a pair with polarized lenses for the benefit of complete UV protection. When driving home, I noticed that the tint on the windows of my car must be polarized as well. When wearing my sunglasses and looking through the tinted windows, I see a distortion that features all the colors of the visible spectrum. I was wondering what it was about polarization that made this distortion when you look through two lenses that have it. Any ideas?
