DESCRIPTION RATINGS & REVIEWS PRESCRIPTION GUIDE

The Saint Laurent SL M146/K sunglasses bring together modern design and sustainable materials in an oversized square frame that makes a statement without trying too hard. Built from recycled acetate on both the front and temples, these frames reduce environmental impact while delivering the same premium feel and vibrant finish you expect from luxury eyewear. Available in classic black or rich havana tortoise, each pair features the signature thin monogram hinge that keeps weight down and comfort up.

Korean Fitting for Better Comfort

These frames are designed with a Korean fitting, which means they're engineered for faces with lower nose bridges, high cheekbones, or broader face shapes. The adjusted nose bridge and temple curvature help the frames sit properly without sliding down or pressing into your cheeks. If standard sunglasses tend to feel tight at the temples or rest on your cheekbones, this fit might be exactly what you need.

Lightweight Construction, Full Protection

The monogram hinge isn't just a style detail—it's functional. By using thin sections on the front and temples, Saint Laurent keeps these oversized frames surprisingly light. You get the bold look of a 56mm square lens without the weight. The frames are prescription-ready, so you can add your Rx lenses and wear them as your everyday pair. All lenses provide 100% UV protection to shield your eyes from harmful UVA and UVB rays.

Measurements: 56mm lens width, 19mm bridge, 145mm temple length. Made in Italy with the quality and attention to detail Saint Laurent is known for.

Frequently Asked Questions

Can I add prescription lenses to the Saint Laurent SL M146/K sunglasses?

Yes, the SL M146/K is fully prescription-ready. You can add single-vision, progressive, or polarized prescription lenses to these frames. The full-rim acetate construction provides a secure lens mount, and the 56mm lens width accommodates most prescription ranges.

What does Korean fitting mean on these sunglasses?

Korean fitting means the frames are designed for faces with lower nose bridges, high cheekbones, or broader face shapes. The SL M146/K features adjusted nose bridge height, modified temple curvature, and angled frame fronts to prevent the sunglasses from sliding down your nose or resting on your cheeks—common issues with standard-fit frames.

Are these sunglasses made from sustainable materials?

Yes, both the front and temples are made from recycled acetate. This material reduces reliance on petroleum-based plastics while maintaining the durability, flexibility, and vibrant color options of traditional acetate. Recycled acetate minimizes waste and lowers the carbon footprint of production.

Do Saint Laurent SL M146/K sunglasses offer UV protection?

Yes, all Saint Laurent sunglasses, including the SL M146/K, provide 100% UV protection (UV400) that blocks harmful UVA and UVB rays. This helps protect your eyes from long-term damage such as cataracts and retinal issues while you're outdoors.

What is the monogram hinge on these sunglasses?

The monogram hinge is a signature Saint Laurent design feature that uses thin metal sections at the hinge points on both the front and temples. This construction reduces overall frame weight for maximum lightness and all-day comfort, especially important on oversized frames like the SL M146/K.

What size are the Saint Laurent SL M146/K sunglasses?

The SL M146/K measures 56mm lens width, 19mm bridge width, and 145mm temple length (56-19-145). This is considered a medium to large size with an oversized square shape that works well for most face sizes, particularly those with broader features.

Saint Laurent SL M146/K vs. Similar Monogram Hinge Styles

If you're drawn to the SL M146/K's lightweight monogram hinge design, you might also consider other frames in Saint Laurent's Monogram Hinge collection. Here's how they compare:

SL M146/K vs. SL M24/K

Both sunglasses share the signature thin monogram hinge construction and Korean fitting, making them equally comfortable for faces with lower nose bridges or high cheekbones. The key difference is frame shape: the M146/K offers an oversized square silhouette that's bold and contemporary, while the M24/K has a different shape profile. Both use recycled acetate and fall in a similar price range ($278-$302), so your choice comes down to which shape better suits your face and style. If you want maximum coverage and a statement look, the M146/K's 56mm oversized square is the stronger choice.

SL M146/K vs. SL M94

The SL M94 is another Monogram Hinge option with the same lightweight construction philosophy. However, it sits at a higher price point ($354-$365) and features a different frame shape and aesthetic. The M146/K offers better value if you're specifically after an oversized square frame with Korean fitting. The M94 might appeal if you prefer its particular style and don't mind the premium.

Bottom line: The SL M146/K stands out in the Monogram Hinge family for its oversized square shape, Korean fitting, and competitive pricing. It's the best choice if you want bold, lightweight frames that sit comfortably on lower nose bridges—all while supporting sustainable materials through recycled acetate construction.
