Watch your style take off wearing the Marc Jacobs Marc 391 eyeglasses. The aviator-style silhouette is such a classic, you might think these frames are all about fashion. And while they could easily get by on looks alone, these frames perform like a dream, too. The large lenses provide correction in a wide field of vision, and the distinctive double bridge reinforces the structure, so you can rely on these good-looking frames for long years of wear. The stainless steel frames are sturdy and lightweight. The Marc Jacobs name at the temple adds the final designer touch to the Marc 391.
