Why do polarizing sunglasses work to reduce glare, which is light reflected off

Question

Why do polarizing sunglasses work to reduce glare, which is light reflected off of a surface?                         

A : Light reflected from horizontal surfaces tends to be horizontally polarized, so the sunglasses’ horizontal polarization cuts the glare.  

B : Light reflected from horizontal surfaces tends to be vertically polarized, so the sunglasses’ horizontal polarization cuts the glare.

C : They don’t; this is just a marketing ploy.

D : Light reflected from horizontal surfaces tends to be horizontally polarized, so the sunglasses’ vertical polarization cuts the glare.

E : They reduce the amount of light entering your eyes.

Explanation / Answer

Polarized sunglasses removes glare by absorbing the incoming horizontal light, while still allowing vertical light. Hence vertical polarization of sunglasses cuts the glare.

Hence correct option: D: Light reflected from horizontal surfaces tends to be horizontally polarized, so the sunglasses’ vertical polarization cuts the glare.
