I wear polarized sunglasses, BUT, if you wear a helmet with face shield, the polarization will play tricks on you. For some things, you will see different colors in each eye. For example, when it's bright out and the sun shines off of the highway, you may see the road in two different ways (one eye may sense a reflection while the other does not). It's hard as heck to describe the phenomenon. Try borrowing some polarized shades and check it out. It was a distraction at first, but no "important" objects were distorted. Cars still looked like cars, animals crossing the street didn't morph into anything and shapes don't change. Why do I continue to wear polarized lenses? Not everything looks goofy thru my shades and I like the idea of protecting myself against cataracts. Ride safe.
