The Maui Jim Equator Sunglasses are designed for full coverage all day long. The caramel tortoise frame is fitted with a HCL Bronze glass polarised lens that features bi-gradient technology that applies mirror above and below both lenses, allowing the middle of the lens to provide a squint affect for you so your eyes are relaxed all day. This guarantees absolute crisp views with a robust wrap silhouette. Maui Jim sunglasses are the best when it comes to visual clarity, protection and enhancement.
