Polarized vs Non-Polarized Aviator Sunglasses. For most people wearing polarized sunglasses it simply helps reduce glare off windows, ice or water; however, for pilots using polarized sunglasses there can be a number of serious problems.
How do polarizing filters work. If I'm not mistaken polarized light consists of light waves vibrating only in a specific direction because the waves vibrating in other directions have been filtered out. I watched a video on youtube and the guy showed how putting 2 polarizing filters together in a certain alignment so as they block the light altogether. Then he demonstrated something weird he put a third polarizing filter in between the other 2 filters and for some reason this counteracted the opacity of the series of filters so that the final filter actually let light through. The inner and outer filters where at 90 degrees to each other while the middle filter was at 45 degrees.
