The Persol Loris 3378S sunglasses bring Italian craftsmanship and vintage-inspired design to a distinctly feminine oval silhouette. Named "Loris" and designed specifically for women, this full-rim acetate frame balances retro charm with modern wearability in a narrow oval shape that flatters a wide range of face shapes.
Persol Heritage and the Loris Design
Since 1917, Persol has stood for "per il sole" — for the sun — and the Loris 3378S carries forward that legacy. The frame showcases Persol's iconic Supreme Arrow hinges, inspired by ancient warriors' swords, which extend from the temples in polished metal. This isn't just decoration; the arrow-shaped hinge is part of Persol's flexible stem engineering that's been refined over decades. The keyhole bridge adds a vintage touch while ensuring a comfortable, secure fit.
Available in ten color and lens combinations, the Loris offers versatility. The Havana tortoise with polarized dark grey lenses delivers classic sophistication and glare-cutting performance. The miele (honey yellow) acetate with blue vintage lenses makes a bolder statement. Black frames with green lenses channel Persol's heritage aesthetic, while the madreterra tortoise with violet lenses offers a contemporary twist. Each acetate frame is handcrafted in Italy using cellulose acetate, a hypoallergenic material that won't irritate skin and develops a richer patina over time.
Fit, Features & Prescription Options
The Loris 3378S is available in two lens widths — 51mm and 53mm — to accommodate different face sizes while maintaining the narrow oval proportions that define the style. The single bridge design and medium-width temples create a balanced profile that won't overwhelm smaller faces. Persol's attention to detail extends to every element: the temples feature the brand's signature three-stripe detailing, and select variants include polarized lenses for superior glare reduction and visual clarity outdoors.
These frames are prescription-ready, accepting single-vision, progressive, and polarized prescription lenses. All lenses provide 100% UV protection. Whether you need corrective lenses or prefer the original sun lenses, the Loris adapts to your vision needs without compromising its refined aesthetic.

Frequently Asked Questions
Are the Persol Loris 3378S sunglasses prescription-ready?
Yes, the Persol Loris 3378S frames are fully prescription-ready and can accommodate single-vision, progressive, and polarized prescription lenses. The acetate frame construction and lens size make them suitable for a wide range of prescriptions, including higher powers. You can customize them with your exact prescription while maintaining the original style and UV protection.
What is the Supreme Arrow on Persol sunglasses?
The Supreme Arrow is Persol's iconic trademark hinge design, inspired by ancient warriors' swords. It's both decorative and functional, featuring an arrow-shaped metal detail that extends from the hinge to the temple. This design has evolved through over 30 variations since Persol's founding, and the current Supreme Arrow represents the brand's commitment to combining aesthetics with engineering excellence.
What face shapes work best with the Persol Loris 3378S oval frames?
The Loris 3378S oval shape is particularly versatile and flatters most face shapes. Oval frames work especially well on square, rectangular, and heart-shaped faces by softening angular features. The narrow oval design also complements round faces by adding gentle definition. The keyhole bridge and balanced proportions ensure a comfortable, flattering fit across different facial structures.
Which Persol Loris 3378S variants have polarized lenses?
The Persol Loris 3378S is available with polarized lenses in the 24/48 colorway (Havana tortoise frame with polar dark grey lenses). Polarized lenses reduce glare from reflective surfaces like water, snow, and pavement, providing superior visual clarity and comfort outdoors. Other colorways feature non-polarized lenses with full UV protection.
How do I choose between the 51mm and 53mm lens sizes?
The lens width determines how the frames fit your face. The 51mm size works best for smaller to medium faces, while the 53mm suits medium to larger faces. As a general rule, the frame width should align with or be slightly wider than the widest part of your face. Both sizes maintain the same narrow oval proportions and design details.
Are Persol sunglasses made in Italy?
Yes, all Persol acetate frames, including the Loris 3378S, are handcrafted in Italy near the brand's historic Turin workshop. Persol has maintained Italian manufacturing since Giuseppe Ratti founded the company in 1917. The frames undergo meticulous production processes with over 10 additional working steps compared to standard frames, ensuring the quality and craftsmanship Persol is known for.

Persol Loris 3378S vs. Similar Persol Frames
If you're drawn to the Persol Loris 3378S, you might also be considering other oval or vintage-inspired Persol frames. Here's how the Loris compares to two popular alternatives in our collection.
Loris 3378S vs. Persol 2803S
Both frames feature oval shapes and Italian acetate construction, but the Loris 3378S is specifically designed for women with a narrower, more refined oval silhouette. The 2803S offers a more unisex fit at a lower starting price ($220.59 vs $363), making it a value-conscious alternative. However, the Loris provides ten distinct color and lens combinations, including the striking miele yellow and madreterra tortoise options, compared to fewer variants in the 2803S. If you prioritize a frame designed specifically for feminine proportions and want more colorway choices, the Loris justifies the premium. If you prefer a slightly larger oval and want to save, the 2803S delivers authentic Persol quality.
Loris 3378S vs. Persol 3171S
The Persol 3171S starts at a more accessible $173.25 and shares the same prescription-ready acetate construction and Italian craftsmanship. However, the 3171S features a different frame shape that may not appeal to those specifically seeking the Loris's distinctive narrow oval design. The Loris 3378S stands out with its keyhole bridge, feminine proportions, and carefully curated color palette that balances vintage and contemporary aesthetics. The 3171S is an excellent choice if you're flexible on frame shape and prioritize value, but the Loris is the better investment if you've fallen for its specific oval silhouette and women's-focused design.
Our recommendation: The Persol Loris 3378S is worth the investment if you want a frame designed specifically for women's faces with distinctive styling and premium colorway options. Choose the 2803S if you prefer a unisex oval at a lower price, or the 3171S if you're open to different shapes and want maximum value while staying within the Persol family.
