The Saint Laurent SL M129 Eyeglasses bring refined Parisian style to your everyday prescription eyewear. This square-frame design features full-rim construction in recycled acetate—a plant-based material that’s lighter, more durable, and more eco-conscious than standard plastic. Available in four transparent finishes (nude, brown, havana, and black), the SL M129 offers a modern, minimalist look that works equally well in the boardroom or at brunch.
Saint Laurent constructs the SL M129 from recycled acetate, a material derived from wood pulp and cotton fibers. Unlike petroleum-based plastics, recycled acetate offers superior durability and flexibility while reducing environmental impact. The transparent finish showcases the material’s natural depth—each frame has subtle variations in tone and clarity that make it genuinely unique. Acetate retains its color better than injection-molded plastic because the dye is integrated during manufacturing, not applied as a coating that can chip or fade.
Measuring 54-18-145mm (lens width, bridge, temple length), the SL M129 fits most face widths comfortably. The square shape balances rounded facial features, while the 18mm bridge and full-rim design provide stability without pressure points. At just a few grams, the acetate frame feels nearly weightless during all-day wear. The single-bridge construction and 145mm temples distribute weight evenly, so you won’t feel them sliding down your nose after a few hours. These frames are prescription-ready and compatible with single-vision, progressive, and high-index lenses.
Saint Laurent’s Italian craftsmanship ensures precise hinge alignment and smooth temple action—details that matter when you’re wearing glasses 12+ hours a day. The transparent acetate won’t yellow or become brittle with normal use, and the material can be easily adjusted by an optician for a custom fit. Whether you need them for computer work, reading, or full-time vision correction, the SL M129 delivers the lightweight comfort and understated elegance Saint Laurent is known for.
