For spring, Costa Sunglasses added five new frame styles — in three sizes — to its Core collection, including Bloke and Kiwa (extra large), Reefton and Tasman Sea (large), and Whitetip (medium). All feature biodegradable resins sourced from reclaimed castor oil, as well as 580 lens technology for 100 percent polarization. The frames come in a variety of colors and are available with glass or polycarbonate lenses from blue-mirrored gray through sunrise yellow. They range in price from $159 to $249.
