Much like the Matheo by Theo, Derek Cardigan puts the nerds in front with these black 7004 models. In a standard looking horn rimmed, acetate wayfarer, Cardigan shows his cunning wit with division and multiplication symbols on the sides and “equal” symbols on the arms. Spring hinges make for a durable and comfortable wear. Geeks never looked so suave than in these 7004s from Derek Cardigan. Available online.
