Original Penguin The Doyle eyeglasses offer a preppy, retro look that’s full of character. Their rectangular rims, keyhole bridge, and metal rivet details offer a handsome, vintage-inspired style that recalls the 1950s, yet is fully at home today. Shark-fin temples sharpen the look at the sides. Original Penguin crafts these full-rim frames in lightweight, sturdy acetate material, for comfortable and durable glasses. For a style that’s full of bookish charm, choose the Doyle eyeglasses for men.
