Introducing the Saint Laurent SL 664 Eyeglasses — a masterful rectangle frame silhouette that brings understated luxury to every day. Designed for a unisex fit and crafted in Japan, these frames pair a rich black front with crystal-tone temples for a look that is at once refined and contemporary. Precision, comfort, and craftsmanship converge in this iconic Saint Laurent style, ideal for the modern professional who values authentic designer eyewear.

Key measurements reveal a balanced, versatile profile: 52 mm lens width, a 20 mm bridge, and a 145 mm temple length, complemented by a 40 mm lens height and a 57 mm diagonal. The full-rim design and the RAC front material reflect a premium, durable build, with a rectangle/square shape that flatters a spectrum of features and expressions.

The SL 664 is offered in classic variations of Beige, Black, and Havana, all in a 52 mm size. The frame combines a Black front with Crystal temples and Transparent lenses to suit both professional and social settings, ensuring timeless versatility across wardrobes and occasions.

Face-shape compatibility is broad: the frame is especially well-suited to Round, Oval, Oblong, Long, Triangle, and Narrow faces, offering a balanced and confident aesthetic that pairs with a wide range of personal styles. The design delivers everyday comfort and lasting wearability, suitable for long days in the office or weekend explorations.
