I got a pair of Oakley Fives 2.0 polorized glasses and I am
very happy with them.  Almost like X-ray vision on clear
water.   Full retail is a little pricey but if you know
someone with a commercial account, you will only pay $65. for
the polorized version.  I have never had to use it, but I hear
the customer service is great too.
