I should specify that mine are prescription. Progressive lenses. When I told my optometrist, which I've been using for more than 25 years, that I wanted prescription sunglasses they said I should pick the frames from their selection and they would handle the lenses. When I told them I wear Maui Jim's they said they are the only lens they cannot reproduce, but that Maui Jim would make lenses with my prescription. So that's what I did. The lenses are incredible.
Perhaps this belongs in the odd statistics thread, but before insurance my Maui Jim prescription sunglasses cost more than the first two cars I bought, combined. Even after insurance they cost more than my first car.
I now own two pair and consider them among the best purchases I have ever made.
