The Porsche Design P’8478 has long been one of the brand's most famous designs and is simply an iconic piece of eyewear. The company continues that legacy with a new model that reinterprets the design with a squared lens shape. The same flip-up interchangeable lens mechanism remains at the core of the design, allowing for wearers to change their lenses based on the day's light conditions. Made in Japan out of lightweight titanium, each frame includes an additional set of lenses and Porsche Design plans to release new lens colors every season.
