The Persol Guido 3393S sunglasses bring Italian heritage and contemporary design together in a pillow-shaped frame that's both distinctive and versatile. Named after the Italian word for "guide," the Guido represents Persol's latest interpretation of its century-old commitment to functional elegance—sunglasses built for real life, not just the runway.
Italian Craftsmanship Since 1917
Persol was founded in Turin by Giuseppe Ratti to create protective eyewear for pilots and race car drivers. The brand name itself—"per il sole," meaning "for the sun"—reflects that original purpose. Today, every Persol frame is still handmade in Italy using cellulose acetate derived from cotton and powdery pigments, creating color variations unique to each pair. The 3393S features a soft pillow shape with a refined double bridge that adds structure without weight, and the signature Supreme Arrow adorns each temple—a design inspired by ancient warrior swords that's been the brand's emblem since the 1930s.
The frame is available in six colorways, from classic black with green lenses (95/31) and Havana tortoise (24/31) to the warm Terra Di Siena brown with light blue lenses (96/56). Polarized options include black with gradient grey (95/M3) and brown with gradient brown (1169M2), cutting glare for driving and water activities. All lenses provide 100% UV protection.
Built for Comfort and Prescription Use
The 3393S is fully prescription-ready, so you can add single vision or progressive lenses through your optician. The acetate construction keeps the frames lightweight, and the 20mm bridge with full-rim design suits a range of face shapes—particularly those with angular features, as the pillow shape softens hard lines. Available in 56mm and 59mm lens widths with 145mm temples, the frame fits medium to larger faces comfortably.
While this model doesn't feature Persol's famous Meflecto flexible temple system (found in the 649 and other classics), the quality acetate and careful Italian construction ensure a secure, balanced fit for all-day wear. The temples are medium width, distributing pressure evenly without pinching.

Frequently Asked Questions
Are Persol Guido 3393S sunglasses prescription-ready?
Yes, the Persol 3393S is fully compatible with prescription lenses. You can have single vision or progressive prescription lenses installed by your optician or through specialized lens services. The full-rim acetate frame securely holds prescription lenses, making these sunglasses a practical choice for those who need vision correction.
What size should I choose for the Persol 3393S?
The 3393S comes in two lens widths: 56mm and 59mm. The 56mm size suits smaller to medium faces, while the 59mm works better for medium to larger faces. Both sizes have a 20mm bridge and 145mm temples. To find your fit, check the measurements on sunglasses you currently own—the three numbers inside the temple arm indicate lens width, bridge width, and temple length.
Does the Persol Guido 3393S have the Meflecto flexible temple system?
No, the 3393S does not feature Persol's patented Meflecto flexible temple system. The Meflecto system, which uses metal cylinders and a flexible steel core inside the temples, is found on classic models like the 649 and 714. However, the 3393S still offers excellent comfort through its quality acetate construction and balanced frame design.
What is the Supreme Arrow on Persol sunglasses?
The Supreme Arrow is Persol's iconic trademark, visible on the temples of the 3393S. Inspired by the swords of ancient warriors, this arrow-shaped hinge detail was created in the 1930s and has become the brand's most recognizable design element. It combines both functional hinge mechanics and distinctive style, making every Persol frame instantly identifiable.
Are the Persol 3393S lenses polarized?
Polarized lenses are available in select colorways of the 3393S, including the 95/M3 (black with gradient grey polarized) and 1169M2 (brown with brown gradient polarized). Other colorways feature standard tinted lenses. All lenses provide 100% UV protection. Check the specific color code when ordering to confirm whether your chosen variant includes polarization.
How does the pillow shape of the 3393S fit different face shapes?
The pillow shape of the 3393S features soft, rounded edges on a rectangular base, making it particularly flattering for angular or square face shapes by softening hard lines. The double bridge design adds visual interest and works well with medium to wider faces. The balanced proportions and full-rim construction provide good coverage without overwhelming smaller features.

Persol Guido 3393S vs. Classic Persol Models
Choosing between Persol models often comes down to whether you want proven heritage or contemporary design. The Guido 3393S represents the brand's modern direction, while models like the 0649 and 3019S offer different value propositions.
3393S vs. 0649: Modern vs. Iconic
The Persol 0649 is the brand's most famous model, created in 1957 for Turin's tram drivers and featuring the patented Meflecto flexible temple system. If you prioritize Persol's signature comfort technology and want a style with decades of cultural cachet, the 0649 is hard to beat. It's also more affordable, starting at $224.
The 3393S takes a different approach. Its pillow shape with double bridge is more contemporary and architectural, appealing to those who want Italian quality without the vintage associations. The 3393S is lighter and more streamlined, though it lacks the Meflecto system. Choose the 3393S if you prefer modern, understated design; choose the 0649 if you want the full classic Persol experience with flexible temples.
3393S vs. 3019S: Premium vs. Value
The Persol 3019S shares the 3393S's contemporary aesthetic with a similar square-pillow shape, but at nearly half the price (starting at $155). Both are acetate frames without Meflecto, making them direct style competitors.
The 3393S justifies its premium with the distinctive double bridge design, more colorway options including polarized variants, and newer 2026 styling. The 3019S is an excellent choice if you want the modern Persol look on a budget, especially in smaller sizes. The 3393S is worth the investment if you want the latest design and more lens options.
Our take: The Guido 3393S sits between heritage and innovation. It's for buyers who appreciate Persol's Italian craftsmanship but want a frame that feels current, not retro. If comfort technology matters most, get the 0649. If budget is key, consider the 3019S. But if you want a distinctive, contemporary Persol that stands apart from the classics, the 3393S delivers.
