In reply to Terry James Walker:
It's worth noting that not all manufacturers advocate polarized lenses for all sports - Adidas for one. They use a different technology based on coatings (polarized lenses basically consist of a membrane within the lens) that reduce incidental light (glare) from all directions other than what you are looking at. They work too - I have a pair of Adidas goggles which I normally only wear when the light is poor and flat, and they are fantastic.
