Kuiaha Bay is one of the most beautiful bays in Hawaii, and Maui Jim named the Kuiaha Bay Sunglasses after it so you can have that same touch of paradise with you wherever you roam. Apart from their sleek, stunning design, these sunglasses utilize ST Glass lenses that offer the best optics possible yet are 20% thinner and lighter than standard glass lenses. They are also durably scratch resistant for excellent longevity. These lenses feature PolarizedPlus 2 technology to eliminate glare, block harmful UV, UVA, and UVB rays, and maximize color transmission. Maui Jim added waterproof and oleophobic coatings on the Kuiaha to shed water and repel grease, and an anti reflective treatment to block annoying glare from behind. The nylon frame fits small faces comfortably Maui Jim recommends this pair for round or oval shaped faces. The frame's saddle style bridge features embedded rubber nosepads for your comfort, and the temples utilize anti corrosive spring hinges that won't rust up when you take this pair of sunglasses out on the ocean.
