The Persol Gae 3391S sunglasses bring contemporary Italian design to one of eyewear's most respected names. Built from premium cellulose acetate and featuring Persol's signature Supreme Arrow on the temples, these square frames balance modern geometry with the brand's century-old commitment to comfort and craftsmanship.
Italian Craftsmanship Since 1917
Persol—derived from the Italian "per il sole" (for the sun)—has been handcrafting eyewear in Turin since Giuseppe Ratti founded the company in 1917. The Gae 3391S carries forward that heritage with acetate frames made from cotton and wood pulp, a material prized for its durability, hypoallergenic properties, and rich color depth. The tortoise and havana finishes show the layered complexity that only quality acetate can deliver, while the clean square shape offers a sharp, structured look that works across face shapes.
The temples feature Persol's iconic Supreme Arrow—inspired by ancient warriors' swords and introduced in the 1930s—along with the brand's patented Meflecto flexible temple system. Meflecto uses metal cylinders embedded in the acetate stems to let the frame adapt to your head shape, eliminating pressure points during all-day wear. It's a 10-step process compared to standard frames, and the difference is noticeable when you're wearing them for hours.
Prescription-Ready & Built to Last
The 3391S is fully prescription-ready, accepting single vision, progressive, and polarized prescription lenses. Available in 53mm and 55mm eye sizes with options ranging from classic green crystal lenses to polarized brown and gradient styles, the frame accommodates different preferences and needs. All lenses provide 100% UVA/UVB protection.
Quality acetate frames like these typically last 5-10+ years with proper care—significantly longer than standard plastic alternatives. The material resists cracking, holds its shape, and won't become brittle over time. For a unisex frame that delivers both style and function, the Gae 3391S is a solid choice whether you're driving, traveling, or just navigating daily life in the sun.

Frequently Asked Questions
Are the Persol 3391S sunglasses prescription-ready?
Yes, the Persol Gae 3391S sunglasses are fully prescription-ready. You can have them fitted with single vision or progressive prescription lenses, including polarized prescription options. The acetate frame construction accommodates custom prescription lenses while maintaining the frame's structural integrity and comfort.
What is the Meflecto system in Persol sunglasses?
The Meflecto system is Persol's patented flexible temple technology, first introduced in the 1930s. It uses metal cylinders inserted into the acetate stems with a flexible steel core, allowing the temples to adapt to any head shape and eliminate pressure points. This system requires over 10 additional manufacturing steps compared to standard frames and provides superior all-day comfort.
What sizes are available for the Persol 3391S?
The Persol Gae 3391S is available in two lens sizes: 53mm and 55mm. Both sizes feature a 19mm bridge and 145mm temples. The unisex square shape works well for medium to large faces, and the Meflecto flexible temples help the frame adapt comfortably to different head sizes.
What is the Supreme Arrow on Persol frames?
The Supreme Arrow is Persol's iconic trademark symbol, visible on the temples of the 3391S. Inspired by the swords of ancient warriors, it was created by founder Giuseppe Ratti in the 1930s to make Persol frames instantly recognizable. The arrow has evolved through over 30 different versions, with the Supreme Arrow being the current signature design used across Persol collections.
Are Persol acetate frames durable?
Yes, Persol acetate frames are highly durable. Made from cellulose acetate derived from cotton and wood pulp, these frames resist cracking, maintain their shape over time, and don't become brittle with age. Quality acetate frames like the 3391S typically last 5-10+ years with proper care, significantly outlasting standard plastic frames which usually last 1-3 years.
Do the Persol 3391S sunglasses have UV protection?
Yes, all Persol 3391S sunglasses provide 100% UVA and UVB protection. The lenses are designed to block harmful ultraviolet rays while delivering optical clarity. Polarized lens options are also available in select colorways, which further reduce glare and enhance visual comfort in bright conditions.

Persol 3391S vs. Other Persol Sunglasses
Choosing between Persol models often comes down to aesthetic preference: do you want the brand's iconic heritage look or a more contemporary design? The Gae 3391S represents Persol's modern direction—clean square lines, sharp angles, and a structured profile that works well with minimalist style.
3391S vs. Persol 0649: Classic vs. Contemporary
The 649 is Persol's most famous model, introduced in 1957 for Turin's tram drivers and famously worn by Steve McQueen. It features a rounded pillow shape with the Victor Flex keyhole bridge and larger lens coverage. The 649 has thicker temples and a wider overall profile, giving it substantial presence but also making it harder to pull off on certain face shapes. If you want instant recognition and classic Italian style, the 649 delivers. But if you prefer modern geometry and a lighter visual weight, the 3391S offers the same Italian craftsmanship in a sharper, more contemporary package. The 3391S also comes in at a slightly lower price point ($329-$393 vs. $224-$427 for the 649, depending on configuration).
3391S vs. Persol 3166S: Modern Alternatives
Both the 3391S and 3166S are contemporary square acetate frames with the Supreme Arrow and Meflecto temples. The choice here is about subtle proportion differences and personal fit preference. The 3166S starts at a higher price ($230-$486) and may offer different sizing options. Try both if possible to see which proportions suit your face better—the differences are in the details, but those details matter when you're wearing them daily.
Why Choose the 3391S?
The Gae 3391S hits a sweet spot: modern square styling that's easier to wear than the iconic 649, full Persol heritage technology (Meflecto, Supreme Arrow, Italian acetate), prescription-ready construction, and a price that's competitive within the Persol lineup. It's a strong choice if you want a contemporary frame from a brand with over a century of eyewear expertise.
