Description

Introducing the Saint Laurent SL 640 Cat-Eye Eyeglasses, a refined expression of modern luxury. Handcrafted in Italy from premium RAC, these frames embody the house’s commitment to craftsmanship and timeless style. The silhouette is bold yet graceful: a classic cat-eye in a deep Black finish, complemented by black temples and transparent lenses. The SL 640 is prescription-ready: you may purchase the frame alone or choose our prescription option and we will fit your lenses and ship within 8–12 days. Frame measurements include a 49 mm lens width, 22 mm bridge, and 140 mm temples, delivering a poised, comfortable fit.

With its flattering cat-eye shape, the SL 640 is especially suitable for Oval, Round, Heart, Diamond, and Narrow faces. The upward sweep of the silhouette adds lift and definition, making it a versatile choice for work, travel, and evenings out. The design nods to luxury eyewear without compromising everyday wear.

Available in four refined colorways — Beige, Black, Havana (Transparent), and Havana — and in a 49 mm size, these frames offer versatile styling options. The front is Black, the temple color is Black, and the lenses present a Transparent finish, ensuring pristine clarity and a sleek, cohesive look across outfits and occasions. Note: this model features a full-rim construction and is not polarized.

Craft and authenticity underpin Ardor Eyewear’s service. As an official stockist of premier designer names, we guarantee genuine Saint Laurent with full manufacturer packaging, competitive pricing, and dedicated support. You can order with confidence online, enjoy easy returns, and select prescription customization—your lenses fitted and shipped in 8–12 days—so you enjoy luxury eyewear that fits your life as seamlessly as your schedule.

Finally, SL 640 embodies a lifestyle for urban professionals who seek authentic designer eyewear that elevates every moment. Pair this frame with a tailored outfit for the office or a polished weekend look, and carry the confidence of owning a piece that is quintessentially Saint Laurent—timeless, sophisticated, and unmistakably premium.
