Light reflecting off most outdoor surfaces such as roadways and bodies of water have less vibrations perpendicular to the surface than parallel to it. What type of polarizing lens would be the most effective at minimizing the glare off these surfaces?
2. The attempt at a solution
This question seems poorly constructed. I know that 2 perpendicular polarizers stacked on top of each other will restrict light... but I really don't understand what it is they are asking. Any insights?
