I have two kids that work at "Sunglass Hut". They both sell lots of expensive sunglasses. Here's what they tell me.
"Maui Jim's" have the best lenses."
They bought me a pair that I've been wearing for over a year and a half now. I've worn sunglass nearly everyday for over 36 years. The Maui Jim's are indeed the best pair I've ever had. The lenses have nearly perfect optics, are polarized, and the most scratch resistant I've ever had, and the frames are ultra light and nearly unbreakable. I've never had a pair hold up as well as them, not even close.
That said, they are way too expensive and I'd never pay that much for a pair myself. I've heard the owner of Maui Jim's has likened selling his sunglasses for that much money to "Printing my own money."
But, both my kids also say that the Maui's are a much better value than Oakleys and the best on the market. They sell both brands, Oakleys are made by the parent company of Sunglass Hut, Maui's are not.
I do know that if you buy from Sunglass Hut they will exchange the glasses or refund your money for, I think, up to 90 days. And, Maui Jim's will replace the lenses for a lifetime for, at present, $60.00, if you send the glasses to them.
Personally, I have always worn polarized sunglasses. They still cut glare better than any of the newer coatings I've tested and I test them all when I visit my kids at work
Tan colored polarized lenses let in more light, and allow you to see underwater a lot better than other shades. They are the best there is for when you're fishing. The darker (grey) lenses are better on very bright days, especially bright days with snow on the ground.
That sums up about all I know about the subject. Hope it helps.
