Best Sunglasses?

[irokcj5]

I have the Costa Man-O-War frames with amber/green coat poly's. I wear bi-focal so they are not available in glass. I love the glasses, but would like to hear others who have prescription bi-focals. I don't know if it was the eyeglass place or Costa, but i had to try 3 times to get the bi-focal right. its ok, now but not great, they put the bi-focal almost to the edge of the glass. Also don't know if it is the Man-o-war frames with the rounded lens or what, but they get me dizzy when I look down at where Im stepping, or turning my head while driving. Anyone else have that trouble with any prescription costa's or Jim Maui's? After insurance, I paid $500. Sure thought I'd get a better set of glasses.
