Another thing i like to mention to people about "what sunglasses REALLY do in terms of protection.... picture this.
When your out fishing and you don't put sun cream on, it doesn't take long for your skin to burn... So if your skin is burning from the UV radiation "what is happening to your eyes"????
BR65 if you want a floating pair of sunglasses look at the Mako Surface..... they float and have a polycarbonate lens ...
