Personally, I've tried a lot of them ... Maui Jims, Costa Del Mars, Hobies, SolarBats ... and Kaenon's.
I've settled on Kaenon's for the time being. Sometimes, you'll have to try something yourself as oppose to hear about them from others. Sunglasses are a very, very personal thing. The fit, the color, the lense shape, etc all play into whether or not a particular brand/model will meet your needs.
For instance, I have heard that Maui Jim's are great ... well, they may have the best optical quality lenses as compared to some. But for me their colors are too DARK ... Hobies are great as are Costa Del Mars as well. But for me they're all too dark. SolarBats, for what they cost me, felt very cheap and the lense fall out too easily ... For me, I wanted something that has a good polarization and good lense quality.
Even the Kaenon's, are somewhat of a compromise. Their frame barely fit's my face/eye's ... still occasionally, my eye lash brush up against the lense causing a smear right in my line of sight. I have to clean them a couple of times a day while fishing. But ... they offer some of the lightest (color wise) polarized lense I've found. I currently use the "28" in gray. That's blocking 28% of the rays I think. They also have a lighter one ... but I forgot the exact percentage. These are not cheap lense, often costing in the neighborhood of $200 ... you can find them on sale now and then for much less.
If you don't mind the SolarBat's, you can get a pair of them from Walmart in their fishing department for ~$18. ... YES Eighteen dollars! ... they don't fit me though ... but I have a round FLAT face ...
