We know that not every moment of your adventures takes place under harsh sun. There's a real need for clear vision all day, every day, so we've created a line of handcrafted eyeglass frames named Costa Optical, inspired by famous underwater landmarks with topographical designs embedded in each eyeglass frame. Costa Del Mar products sold by authorized sellers, like Amazon, are eligible for all manufacturer warranties and guarantees.
