Experience the understated drama of Saint Laurent with the SL 665 sunglasses. This unisex frame blends a contemporary rectangle silhouette with the house’s signature refinement, creating a look that transitions effortlessly from the office to the city streets. Crafted for versatility as much as for luxury, the SL 665 offers a timeless profile that remains relevant across seasons, inviting you to express confidence and sophistication in every moment.

Frame construction and color: The front main material is listed as MET, delivering a crisp, durable foundation, while the Black front and Crystal temples create a refined contrast that catches the light from every angle. The design is offered in three elegant colorways—Black, Ivory, and Silver—across a 56 mm lens width, ensuring a balanced fit for a range of face shapes. The lens base S04 reinforces a classic, comfortable geometry for daily wear.

Face shapes and fit: The rectangle/square frame is inherently versatile. It flatters round and oval faces by adding structure and balance, while also complementing heart-shaped and oblong profiles through its confident proportions. For those with long or narrow features, the 56 mm width provides comfortable coverage without overpowering the features.

Prescription-ready customization: With Ardor Eyewear, you can buy the frame alone or opt for prescription lenses. Our lab will fit your personalized lenses and ship in 8–12 days, ensuring a precise, professional result that preserves the frame’s craftsmanship.
