Re: Polorized glasses.Yes or NO?
Here's a couple of points to ponder. I always wear polarized glasses outdoors. Once you see the benefit of glare reduction while driving, you will too. If they are not marked or if there is any doubt, just put one pair in front of another. Turn one pair 180 degrees to the other, in other words 1 horizontal and one vertical. The view through that lens will go completly opaque. The light will be polarized out in both planes.
Another important consideration is the color of the underside of the brim on your hat. White or bright,light colors will reflect glare from the water onto your face,the backs of your sunglass lenses and into your eyes. Ever get a headache even with a hat and good glasses ? The brim may be the culprit !
