DESCRIPTION RATINGS & REVIEWS PRESCRIPTION GUIDE

The Saint Laurent New Wave SL 428 Sunglasses bring refined minimalism to a rectangular silhouette. Built from stainless steel, this full-rim frame balances structure with a lightweight feel that works for all-day wear. The 56mm lens width and 17mm bridge deliver medium coverage, while the sleek metal construction keeps the profile clean and modern.

The Saint Laurent logo appears in high relief along the temples—understated branding that doesn't shout. The black-on-black colorway shown here is versatile enough for everything from tailored workwear to weekend casual, and the rectangular shape flatters most face types, especially oval and round faces looking for a bit of angularity.

The lenses are nylon with 100% UV protection, shielding your eyes from UVA and UVB rays. Stainless steel frames offer solid corrosion resistance and shape retention—they hold up to daily handling, temperature shifts, and the regular wear that comes with being your go-to pair. The 145mm temples and single-bridge design keep the fit secure without pressure points.

These frames are prescription-ready. If you need vision correction, you can add single-vision or progressive lenses during checkout, turning them into functional sun protection that actually works for your eyes. The New Wave collection reflects Saint Laurent's Paris-meets-rock-and-roll aesthetic—sharp lines, no excess, and a confidence that doesn't need embellishment.

Made in Italy, the SL 428 ships with a Saint Laurent case and cleaning cloth.

Frequently Asked Questions

Can I get prescription lenses in the Saint Laurent SL 428 sunglasses?

Yes, the Saint Laurent New Wave SL 428 sunglasses are prescription-ready. You can add single-vision or progressive prescription lenses during checkout. The rectangular shape and 56mm lens width provide enough surface area to accommodate most prescriptions, and you can choose from polarized, high-index, or anti-reflective lens options to match your needs.

Do Saint Laurent SL 428 sunglasses have UV protection?

Yes, all Saint Laurent SL 428 sunglasses come with 100% UV protection. The nylon lenses block 100% of UVA and UVB rays, protecting your eyes from harmful sun exposure. This UV400 protection is standard across the Saint Laurent eyewear collection and helps reduce the risk of long-term eye damage from ultraviolet radiation.

What is the frame material of the SL 428 sunglasses?

The Saint Laurent SL 428 features a stainless steel frame with enamel details on the end tips and temples. Stainless steel offers excellent durability, corrosion resistance, and shape retention for everyday wear. The metal construction keeps the frame lightweight while maintaining structural integrity, and the material is generally hypoallergenic, making it suitable for sensitive skin.

What are the dimensions of the Saint Laurent SL 428?

The SL 428 measures 56mm lens width, 17mm bridge width, and 145mm temple length (56-17-145). This is a medium-sized frame that fits most adult faces comfortably. The 56mm lens provides good coverage without being oversized, and the 17mm bridge works well for average nose widths. The rectangular shape offers a modern, unisex fit.

Are the Saint Laurent SL 428 sunglasses unisex?

Yes, the SL 428 is designed as a unisex rectangular frame. While it's tagged for men in some listings, the clean lines, medium sizing, and balanced proportions make it suitable for anyone. The 56mm lens width and sleek metal construction work across face shapes and personal styles, reflecting Saint Laurent's modern, gender-neutral design approach.

What comes with the Saint Laurent SL 428 sunglasses?

Each pair of Saint Laurent SL 428 sunglasses comes with an authentic Saint Laurent case and cleaning cloth in the original packaging. All sunglasses sold at Designer Optics are 100% authentic, sourced directly from authorized distributors, and include the manufacturer's original accessories and branding to ensure you receive a genuine product.

Saint Laurent SL 428 vs. Similar Metal Frames

If you're drawn to the Saint Laurent New Wave SL 428, you're likely considering other metal frames in the brand's lineup. Here's how the SL 428 stacks up against comparable options in our catalog.

SL 428 vs. SL 422 (New Wave Collection)

Both the SL 428 and SL 422 belong to the New Wave collection and share the same stainless steel construction and rectangular aesthetic. The SL 428 comes in at $320.31, while the SL 422 is priced higher at $385.61. If you're after the New Wave look and want to save about $65, the SL 428 delivers the same premium metal build and Italian craftsmanship. The main differences come down to temple detailing and available colorways—the SL 428's enamel accents and high-relief logo offer a slightly more refined finish at a better price point.

SL 428 vs. SL 28 METAL (Classic Collection)

The SL 28 METAL represents Saint Laurent's Classic collection, with a more heritage-driven design and a price tag of $384.55–$397.75. Where the SL 428 leans modern and minimalist, the SL 28 offers a more traditional, aviator-inspired silhouette. If you prefer clean, contemporary lines and want to stay under $325, the SL 428 is the smarter pick. If you're drawn to classic shapes with a vintage edge and don't mind the premium, the SL 28 is worth the investment.

SL 428 vs. SL 309 (Classic Collection)

At $311.54, the SL 309 is the closest price competitor to the SL 428. Both are metal frames with similar sizing and Italian construction, but they come from different collections—New Wave vs. Classic. The SL 428's enamel temple details and high-relief branding give it a more fashion-forward edge, while the SL 309 offers a more understated, timeless look. If you want modern detailing and the New Wave aesthetic, go with the SL 428. If you prefer subtle, classic styling, the SL 309 is a solid alternative at nearly the same price.

Our take: The SL 428 offers the best value in Saint Laurent's metal frame lineup if you want New Wave design, premium stainless steel construction, and distinctive enamel detailing—all for under $325. It's a versatile, everyday frame that works across styles without sacrificing quality or brand prestige.
