The new Bollé Chronoshield is both retro and very current. The name and design of the sunglasses harkens to 1986, the year Bollé released the original Chronoshield. The current model, pictured, uses the company’s Phantom lens, which is photochromic – providing Cat. 1 to Cat. 3 protection – and which increases contrast when you are out on the road. An anti-fog treatment will keep things clear when you heat up in cool weather.
