Description

Introducing the Saint Laurent SL 646/F Eyeglasses, a refined rectangular and square silhouette that epitomises modern luxury. Rendered in black, this frame pairs a sleek premium metal frame with authentic Italian tailoring. The front main color is Black, the temple main color is Black, and the lenses are Transparent, ensuring clarity with a discreet, elegant presence. Crafted in Italy from a premium metal frame (MET), the SL 646/F balances durability with comfort, featuring an 18 mm bridge and 145 mm temple length. Each detail reflects authentic designer craftsmanship and the enduring style Saint Laurent is known for.

For those who require vision correction, this frame is ready for prescription-ready customization. You can buy the frame-only or opt for prescription, and our team will fit your lenses and ship within 8–12 days. As the UK official stockist of Saint Laurent eyewear, Ardor Eyewear guarantees authentic packaging and full manufacturer standards.

Face shape guidance: the rectangular and square geometry typically flatters oval and round faces by adding definition, while also complementing oblong and long faces that seek balance. Those with heart-shaped or narrow faces may appreciate the frame's proportion against their features.

Available in two subtle colour options: Black and Silver (Size: 53 mm). The 53 mm lens width, 45 mm lens height, and 18 mm bridge combined with 145 mm temples ensure a comfortable, secure fit for daily wear—perfect for a cosmopolitan, professional lifestyle. The black variant exudes classic luxury, while the Silver offers a contemporary twist—each pair pairs beautifully with a tailored wardrobe.

Invest in enduring style and precise vision with the Saint Laurent SL 646/F. Experience Ardor Eyewear’s commitment to authenticity, convenience, and personalised service. Explore the two color options—Black and Silver—and select your preferred lens option today.
