Saint Laurent SL Logo SL 641 Sunglasses

Saint Laurent SL 641 sunglasses: the boldness of French luxury

Saint Laurent has never stopped reinventing elegance, and the SL 641 sunglasses are a shining example of that. With their pronounced cat eye silhouette and full acetate frame, they embody what the house does best: a design that is both contemporary and timeless, created for women who refuse to go unnoticed.

The full-rim frame and its slightly exaggerated cat eye shape give these glasses a bold, assertive character. This is not a discreet pair — it is a confident style statement, equally at home on a terrace or at an evening event. The Saint Laurent logo on the temples completes the look with an immediately recognisable visual signature, a symbol of belonging to the Parisian luxury world.

An acetate frame: a choice of quality and artisanal craftsmanship

Saint Laurent chose acetate for the SL 641, and that is no coincidence. This noble material, rooted in the great eyewear-making tradition, offers a richness of hues and depth that ordinary plastic simply cannot match. Acetate is worked by hand, polished, and given time — all details that make a difference when you wear these glasses every day. Its relative lightness and durability make it the ideal choice for a pair designed to accompany your life, not merely to sit in a case.

The full-rim frame envelops the lenses with a thickness that asserts its character. This is far from the thin, understated frames you might find elsewhere — the material is visible, present, and that is precisely what makes this model so compelling.

Lenses designed for optimal visual comfort

The SL 641 sunglasses are fitted with lenses offering 100% UV protection. Optical quality is fully on point, with non-polarised lenses that ensure natural vision and true colour rendering. Whether you are by the sea, in the city, or enjoying a countryside weekend, these lenses are designed to meet the demands of everyday life while preserving your visual comfort.

These glasses are also prescription-adaptable, meaning it is possible to fit them with corrective lenses according to your prescription. Great news for those who need vision correction and refuse to sacrifice style for functionality.

The dimensions of the SL 641 frame

To help you choose with complete confidence, here are the precise measurements of this model: lens width 52 mm, bridge 20 mm, temple length 145 mm, and lens height 43.2 mm. These dimensions make it a model suited to a wide range of face shapes, with a slight tendency to flatter oval and round faces thanks to the lifting effect of the cat eye shape.

The frame is manufactured in Italy, in keeping with the exacting quality standards of Saint Laurent, a subsidiary of the Kering group.

Frequently asked questions about Saint Laurent SL 641 sunglasses

Are the SL 641 suitable for all face shapes?

The cat eye shape of the SL 641 is particularly flattering for round and oval faces, as the upswept corners visually elongate the gaze. It can also work very well on a square face by softening the angles. If you are unsure, our qualified opticians are available to advise you in store or remotely.

Can I have corrective lenses fitted in the SL 641?

Yes, absolutely. This model is prescription-adaptable. Simply share your prescription with us and our qualified opticians will take care of fitting your corrective lenses, ensuring both the prescription and the aesthetics of the frame are respected.

How do I care for a Saint Laurent acetate frame?

Acetate is easy to care for with a slightly damp microfibre cloth. Avoid harsh chemical products and never leave your pair in a car in direct sunlight — excessive heat can warp acetate over time. A hard case is recommended for transport.
