We're known for polarized sunglasses with the clearest lenses and toughest frames. But not every moment of our adventures takes place under harsh sun - we pack our gear in the dark of morning, read a novel on the flight to elsewhere and plot the next day's course on an old map at night. There’s a real need for clear vision all day, every day, so we’ve created a line of meticulously crafted frames named Costa Optical, inspired by famous underwater places with topographical designs embedded in each frame.
