These prescription glasses are designed with the fashion-loving trendsetter in mind. The large square frames are crafted from acetate and beveled around the front for a modern 3D effect. Notice the iconic JJ metal trim adorning the lugs and temples, the Marc Jacobs logo lettering positioned cheekily along the brow bar, and the luxurious logo plaques on the inner arms and tips. The five-washer hinges ensure durability.
