Hi There, I am a registered optician and I guess for my money I would buy the Maui Jim polorized glasses. Maui Jim has several layers of anti reflective components that make it easy to see through the water and they also have a hydrophobic coating the sloughs off water - they are also usually glass lenses which makes them more durable.
I also work at Costco, not that I am plugging them but they have the best prices on close out models. For under $100 you can get a good pair of glasses - check the return policy at the store as you buy as you might be able to try them out for a few days to see if you like them.

Good luck
Crystal
