DESCRIPTION RATINGS & REVIEWS PRESCRIPTION GUIDE

The Saint Laurent SL 628 Sunglasses bring the brand's signature rock-and-roll edge to a bold flat-top square frame. Part of Saint Laurent's Naked Wirecore collection, these sunglasses showcase an innovative construction technique: a metal wirecore embedded within transparent crystal acetate temples, creating a striking visual contrast against the solid black front. The laser-engraved Saint Laurent logo runs along the exposed wirecore, adding an unmistakable luxury signature.

Naked Wirecore Design

The wirecore isn't just for show. This metal core runs through the temples, providing structural reinforcement while maintaining the flexibility and comfort of acetate. The transparent crystal temple material allows the shiny metal wirecore to remain visible—a design detail that sets these frames apart from conventional acetate sunglasses. The flat-top square shape features Saint Laurent's signature corner angles, creating a strong, masculine silhouette that works particularly well on round or oval face shapes.

Sustainable Materials & UV Protection

The frame is constructed from 80% recycled acetate, reducing environmental impact without compromising durability or finish quality. The dark grey bio nylon lenses offer 100% UVA/UVB protection and a 43mm lens height that provides excellent coverage. At 55-19-145mm, these sunglasses offer a large fit suitable for medium to wider faces. The integrated nose pads ensure a comfortable, secure fit throughout the day.

Prescription-Ready Luxury

These sunglasses are prescription-ready, so you can add your Rx lenses and enjoy the same bold Saint Laurent style with vision correction. The full-rim construction and single bridge design accommodate most prescription types, making them a practical choice for anyone who needs corrective lenses but refuses to compromise on style. Made in Italy with the craftsmanship Saint Laurent is known for, the SL 628 arrives with an authentic case and cleaning cloth.

Frequently Asked Questions

Are the Saint Laurent SL 628 sunglasses prescription-ready?

Yes, the SL 628 sunglasses are fully prescription-ready. The full-rim acetate frame and 43mm lens height accommodate single vision, progressive, and reading prescriptions. Our licensed opticians can fit your Rx lenses while maintaining the frame's structural integrity and the distinctive wirecore design.

What is the Naked Wirecore technology in the SL 628?

The Naked Wirecore is Saint Laurent's innovative construction technique featuring a metal wirecore embedded in transparent crystal acetate temples. The metal core provides structural strength and flexibility, while the transparent material keeps it visible for a distinctive look. The Saint Laurent logo is laser-engraved directly onto the exposed wirecore in a super-shiny finish.

What face shapes work best with the SL 628 square frames?

The SL 628's flat-top square shape with bold corner angles works best on round and oval face shapes, adding definition and structure. The 55mm lens width and 19mm bridge offer a large fit suitable for medium to wider faces. The strong, masculine silhouette balances softer facial features.

Do the SL 628 sunglasses offer UV protection?

Yes, the SL 628 features bio nylon lenses that provide 100% UVA/UVB protection, shielding your eyes from harmful ultraviolet rays. The dark grey solid lenses also reduce glare and eye strain in bright outdoor conditions.

What are the measurements of the Saint Laurent SL 628?

The SL 628 measures 55mm lens width, 19mm bridge width, 145mm temple length, and 43mm lens height. This is considered a large fit, best suited for medium to wider faces. The measurements are typically printed on the inside of the temple arm.

Are the SL 628 frames made from sustainable materials?

Yes, the SL 628 is constructed from 80% recycled acetate and 20% bio nylon lens material. Recycled acetate reduces waste and carbon footprint while maintaining the same durability, flexibility, and color vibrancy as traditional acetate. This makes the SL 628 a more environmentally conscious choice without sacrificing luxury or quality.

Saint Laurent SL 628 vs. SL 318 vs. SL M94

Choosing between Saint Laurent's square sunglasses comes down to design philosophy and budget. The SL 628 represents the brand's most innovative approach with its Naked Wirecore technology—a metal core embedded in transparent crystal temples that's both functional and visually striking. At $341, it sits in the mid-to-upper range of Saint Laurent's collection and showcases the brand's commitment to sustainable materials with its recycled acetate construction.

The Saint Laurent Classic SL 318 offers a more traditional square frame at a lower price point ($186-$233). It's an excellent choice if you want the Saint Laurent name and quality without the architectural wirecore detail. The SL 318 delivers clean, understated style—perfect for those who prefer classic acetate frames without visible structural elements.

The Saint Laurent Monogram SL M94 ($354-$365) competes directly with the SL 628 on price but takes a different design direction. Instead of the modern wirecore, it features the iconic YSL monogram logo—a choice for customers who want instantly recognizable branding. Both are premium options, but the SL 628's transparent temples and exposed metal core make a bolder, more contemporary statement.

If you value innovation, sustainability, and distinctive design details, the SL 628 is the clear winner. Its wirecore construction isn't just aesthetic—it provides real structural benefits while creating a look that's unmistakably Saint Laurent. For those seeking a more budget-friendly or traditionally branded option, the SL 318 and SL M94 are solid alternatives within the same family.
