So, I was sure there was a thread about this very topic (or a thread that spoke to this very topic) where Prof and I had a bit of a back and forth about sunglasses and why he thought the last pair I bought (almost 3 years ago) should have been polarized. Well, I just bought new prescription sunglasses and they are polarized. So, I would like Prof (and anyone else who wants to) to tell me why I made a good decision. Everything I've ever heard or read suggests they're better...but WHY are the better. What did I pay an extra $66 for?
