The Saint Laurent Monogram SL M103 sunglasses bring a fresh, angular take on the brand's signature cat-eye shape. This isn't your standard retro frame—the SL M103 pushes the silhouette into sharper, more geometric territory, with bold lines and a distinctive rectangular-meets-cat-eye profile that reads modern and confident.
Design & Construction
Built from premium acetate in a full-rim construction, the SL M103 features a redesigned temple where the iconic YSL logo sits in a new, more prominent position. The frame measures 58mm lens width, 15mm bridge, and 145mm temple length—a medium-to-large fit that works across most face shapes. The angular top line and flared outer edges create a strong, feminine statement without veering into oversized territory. Available in five distinct colorways, including classic black with grey gradient lenses, havana tortoise with green lenses, and a photochromatic "Blue & Beyond" option that adapts to changing light.
Lenses & Protection
The SL M103 comes standard with 100% UVA/UVB protection. Select variants feature polarized lenses to cut glare, while the gradient lens options offer a smooth transition from darker coverage at the top to lighter tint below—ideal for driving or outdoor wear. The nylon lenses are impact-resistant and optically clear. This frame is prescription-ready, compatible with single-vision, progressive, and polarized Rx lenses, making it a practical choice if you need vision correction without sacrificing style.
Who It's For
The SL M103 suits anyone drawn to bold, architectural eyewear with a Parisian edge. The cat-eye shape flatters oval, heart, and square face shapes particularly well, adding balance and lift. It's a go-to for those who want a frame that stands out but still pairs easily with everything from tailored blazers to casual denim. Comes with a Saint Laurent protective case and cleaning cloth.

Frequently Asked Questions
Can I get prescription lenses in the Saint Laurent SL M103 sunglasses?
Yes, the SL M103 is fully prescription-ready. The frame's 58mm lens width and full-rim acetate construction provide ample space for single-vision, progressive, and polarized prescription lenses. You can customize with high-index materials for stronger prescriptions, anti-reflective coatings, and gradient or solid tints.
What size are the Saint Laurent SL M103 sunglasses?

Saint Laurent SL M103 vs. SL M115 vs. Prada 12XS
If you're drawn to the Saint Laurent SL M103's angular cat-eye shape, you might also be considering the Saint Laurent SL M115 or the Prada 12XS. Here's how they stack up.
Saint Laurent SL M103 vs. SL M115
Both are modern Saint Laurent cat-eye frames built from premium acetate, but the SL M103 stands out with its repositioned YSL logo and more geometric, rectangular-influenced silhouette. The M103 is part of the evolved Monogram collection, offering five colorways including polarized and photochromatic options. The SL M115 maintains a cat-eye shape but with a different temple design. If you want the latest Monogram evolution with the boldest angular lines, the M103 is the choice. If you prefer a slightly different aesthetic within the same brand family, the M115 at $302.34 is worth a look.
Saint Laurent SL M103 vs. Prada 12XS
The Prada 12XS offers Italian luxury at a lower starting price ($162.09), making it an attractive alternative if you're comparing designer cat-eye frames. Prada's design language leans toward classic elegance with the iconic triangle logo, while the SL M103 brings a sharper, more architectural edge rooted in Saint Laurent's Parisian rock-and-roll aesthetic. The M103's geometric lines and repositioned YSL branding make a bolder statement. If you prioritize cutting-edge design and that distinctive Saint Laurent attitude, the M103 justifies the premium. If you're after timeless Italian style with more budget flexibility, the Prada 12XS is a strong contender.
Our take: The Saint Laurent SL M103 is the frame for those who want the most modern, angular interpretation of the cat-eye shape. Its geometric silhouette, repositioned YSL logo, and evolved Monogram design make it a standout in the luxury eyewear space—perfect if you're after bold, architectural style with Parisian edge.
