Lulu Guinness takes a timeless silhouette to new, contemporary heights in these L905 eyeglasses for women. The striking cat-eye frames are made in hypoallergenic cellulose acetate—a lightweight plastic made from cotton and wood fibers. The sleek skull temples widen slightly at the tips for added grip behind the ears, and feature flexible spring hinges that retain their balance for a comfortable, secure fit. A pronounced browline and squared-off endpoints add to the retro-inspired aesthetic of these L905 glasses from Lulu Guinness.
