DESCRIPTION RATINGS & REVIEWS PRESCRIPTION GUIDE

The Gucci GG1991S Sunglasses bring one of fashion's most recognizable heritage details to a modern square frame. These men's sunglasses feature the iconic Web stripe running down the temples—Gucci's signature green-red-green or blue-red-blue color combination that's been a house code since the 1950s. It's a direct nod to the brand's equestrian roots and Italian luxury DNA.

Square Flat-Top Frame in Recycled Acetate

The GG1991S has a squared flat-top shape that works well on round or oval faces, adding definition without being overly aggressive. The full-rim frames are made from recycled acetate, a plant-based material that's more durable and flexible than standard plastic. Acetate resists breakage, molds comfortably to your face over time, and is hypoallergenic—good news if you have sensitive skin. The material also holds color depth well, which is why the translucent brown and grey variants look richer than typical injection-molded frames.

The temples are injection-molded with the Web stripe detail and feature Gucci lettering. At 52-21-145mm (lens width, bridge, temple length), this is a medium fit that suits most face sizes. The 21mm bridge sits comfortably without pinching, and the 145mm temples provide a secure fit without pressure behind the ears.

Bio Nylon Lenses with 100% UV Protection

The lenses are made from bio nylon, a lightweight and impact-resistant material that blocks 100% of UVA and UVB rays. The GG1991S is not polarized, but the solid lens tints (green, grey, or blue depending on the variant) provide good glare reduction for everyday wear. These sunglasses are prescription-ready, so you can have your optician fit them with single-vision, progressive, or even polarized prescription lenses if needed.

Who They're For

The GG1991S sits in Gucci's contemporary lineup—not as bold as the oversized shield styles, but more distinctive than a basic wayfarer. They're for guys who want recognizable luxury branding without wearing a billboard. The Web stripe is subtle enough for the office but unmistakable to anyone who knows Gucci. The flat-top square shape has a slight retro vibe that pairs well with tailored casual wear or streetwear.

Frequently Asked Questions

Can I add prescription lenses to the Gucci GG1991S sunglasses?

Yes, the GG1991S is prescription-ready. The full-rim acetate frame can accommodate single-vision, progressive (no-line bifocal), and even polarized prescription lenses. Your optician will remove the original bio nylon lenses and fit your custom prescription lenses into the frame. The 52mm lens width and 21mm bridge provide enough surface area for most prescription ranges.

What does the Web stripe on Gucci sunglasses mean?

The Web stripe—the green-red-green or blue-red-blue bands on the temples—is one of Gucci's oldest and most iconic design elements. It was introduced by Rodolfo Gucci in the 1950s and was originally inspired by the girth straps used on equestrian saddles. Today, it sits alongside the interlocking GG logo as a signature house motif across Gucci accessories, including eyewear.

What size are the Gucci GG1991S sunglasses?

The GG1991S measures 52-21-145mm: a 52mm lens width, 21mm bridge width, and 145mm temple length. This is considered a medium fit in Gucci's sizing system. The lens height is approximately 41mm. If you typically wear 52-54mm lens widths in other brands, the GG1991S should fit comfortably.

Are Gucci GG1991S sunglasses polarized?

No, the GG1991S comes with non-polarized bio nylon lenses. However, if you order prescription lenses for this frame, you can request polarized prescription lenses, which will reduce glare from reflective surfaces like water, snow, or car hoods while also correcting your vision.

Do Gucci GG1991S sunglasses provide UV protection?

Yes, the GG1991S lenses block 100% of UVA and UVB rays. This is standard across Gucci sunglasses and helps protect your eyes from long-term damage like cataracts and retinal issues caused by prolonged sun exposure.

What is the frame material of the Gucci GG1991S?

The GG1991S frame is made from recycled acetate, a plant-based material that's more durable, flexible, and hypoallergenic than standard plastic. The temples are injection-molded with the Web stripe detail. Acetate frames can be adjusted by an optician for a custom fit and tend to hold their shape better over time than cheaper plastic frames.

Gucci GG1991S vs. GG0001SN: Web Stripe Showdown

If you're drawn to Gucci's iconic Web stripe, you're likely choosing between the GG1991S and the GG0001SN. Both feature the signature green-red-green stripe on the temples and square acetate frames, but there are key differences.

The GG0001SN is the more compact option with the same 52mm lens width but a slightly more rectangular (less flat-top) shape. Its biggest advantage is the polarized lenses, which cut glare from water, snow, and reflective surfaces—ideal if you spend time near water or driving in bright conditions. It's also more affordable at $202–$235. However, polarized lenses can limit your prescription options if you need vision correction.

The GG1991S has a modern flat-top square shape that adds more definition to round or oval faces. The bio nylon lenses aren't polarized, but that makes it easier to fit with prescription lenses if needed. The flat-top silhouette is more contemporary and pairs well with streetwear or tailored casual looks. At $241.88, it's a bit more, but you're getting a more current design.

Bottom line: Choose the GG0001SN if you want polarized lenses and a lower price. Go with the GG1991S if you prefer the flat-top shape, plan to add prescription lenses, or want a more modern take on the Web stripe aesthetic.

Gucci GG1991S vs. GG0746S: Web Stripe or GG Logo?

The GG0746S offers a similar square frame but swaps the Web stripe for Gucci's interlocking GG logo on the temples. It's a question of branding preference: the Web stripe is more heritage-focused and equestrian-inspired, while the GG logo is the brand's most universal symbol.

The GG0746S is also more affordable at $177–$211, making it a good entry point into Gucci eyewear. Both are prescription-ready and offer 100% UV protection. If you want the tri-color stripe that's instantly recognizable as Gucci's heritage motif, the GG1991S is the better choice. If you prefer the classic GG logo and want to save a bit, the GG0746S delivers.
