The Prada B11S sunglasses bring Italian luxury to a modern rectangular silhouette. Part of Prada's Signature collection, these men's frames showcase the brand's refined approach to eyewear design—clean lines, premium materials, and subtle details that set them apart from ordinary sunglasses.
Design Details That Matter
The B11S is built from cellulose acetate, a material Prada has mastered over decades. The frames feature a polished finish that feels substantial without being heavy, and the full-rim construction provides durability for daily wear. Look closely and you'll spot the sophisticated triangular rivets on the front—a signature detail that adds visual interest without shouting for attention. The temples are where Prada really shows its hand: wide acetate arms carry elongated metal plaques engraved with the Prada logo, a design element that's become instantly recognizable.
Available in multiple finishes—solid black with dark grey or blue vintage lenses, classic tortoise with green polarized lenses, root tortoise, and transparent terra with brown lenses—the B11S adapts to different styles while maintaining its core identity. The rectangular shape works particularly well for men with round or oval face shapes, adding structure and balance.
Prescription-Ready and Built to Last
These frames are prescription-ready, which means you can add single vision, progressive, or specialized lenses to match your vision needs. The 55mm and 57mm lens widths accommodate most prescriptions, and the acetate frame hides lens edges better than metal alternatives—a practical advantage if you need stronger correction. The high bridge fit is designed for those with higher nose bridges, providing a secure, comfortable fit that doesn't slide down throughout the day.
Select variants include polarized lenses that cut glare from water, pavement, and other reflective surfaces—useful if you spend time driving or near water. All lenses provide UV protection. Made in Italy and shipped with the original Prada case, cleaning cloth, and authenticity documentation, the B11S represents the kind of quality Prada has built its reputation on since 1913.

Frequently Asked Questions
Are Prada B11S sunglasses prescription-ready?
Yes, the Prada B11S frames are fully prescription-ready. You can add single vision, progressive, or specialized prescription lenses to these frames. The full-rim acetate construction is ideal for prescription lenses because the thicker frame helps conceal lens edges, which is especially beneficial if you have a higher prescription. The frames accommodate various lens materials including high-index, Trivex, and polycarbonate options.
What face shapes work best with the Prada B11S rectangle frames?
The Prada B11S rectangular shape is particularly well-suited for round and oval face shapes. The angular lines of the rectangle frame add definition and structure to softer facial features. The frames are available in two lens widths—55mm for narrower faces and 57mm for regular fit—allowing you to choose the size that best complements your proportions.
What is the high bridge fit on the Prada B11S?
The Prada B11S features a high bridge fit, which is designed for people with a higher nose bridge and lower cheekbones. This fit provides a more secure and comfortable position on the face, preventing the frames from sitting too low or sliding down. It's a good choice if the bridge of your nose is above the level of your pupils.
Are polarized lenses available for the Prada B11S?
Yes, several color variants of the Prada B11S come with polarized lenses, including the Classic Tortoise with Green Polar lenses (15W04D) and the Root Tortoise with Green Polar lenses (17N20G). Polarized lenses reduce glare from reflective surfaces like water, pavement, and car hoods, making them ideal for driving and outdoor activities. Non-polarized options are also available in other color combinations.
What are the measurements of the Prada B11S sunglasses?
The Prada B11S is available in two sizes: 55mm and 57mm lens width. Both sizes feature a 17mm bridge width and 145mm temple length. The lens height is approximately 33mm. These measurements make the B11S suitable for narrow to regular face widths, with the frame offering good coverage without being oversized.
What material are Prada B11S frames made from?
The Prada B11S frames are made from cellulose acetate, a premium material derived from natural fibers. Acetate is highly durable, resistant to temperature changes, hypoallergenic, and offers a robust range of colors and finishes. Prada shapes and polishes the acetate to achieve a slightly silky, glossy finish. The temples feature metal plaques with the Prada logo, and the front includes subtle triangular metal rivets as design accents.

Prada B11S vs. Prada 17WS Symbole: Classic vs. Contemporary
Both the Prada B11S and the Prada 17WS Symbole represent modern Italian eyewear at its finest, but they take different design approaches. The B11S leans into a refined rectangular silhouette with subtle branding—triangular rivets and elongated temple plaques—that works across professional and casual settings. The 17WS Symbole, part of Prada's more fashion-forward Symbole collection, offers a different aesthetic vocabulary that appeals to those seeking a more distinctive look.
In terms of construction, both frames are made in Italy using premium acetate and are fully prescription-ready. The B11S is available in two lens widths (55mm and 57mm) with a high bridge fit designed for oval and round face shapes. Its rectangular shape adds structure to softer facial features, making it a versatile choice for daily wear. The B11S also offers multiple lens options including polarized variants in the tortoise colorways, which is practical for driving and outdoor activities.
The price ranges overlap significantly—the B11S runs $404-$642 while the 17WS Symbole is priced at $433-$577—so the decision comes down to design preference rather than budget. If you want a classic rectangular frame that will remain relevant for years and works in any context, the B11S is the safer choice. Its understated elegance and clean lines make it the kind of frame you can wear every day without thinking twice. The triangular rivet details and metal logo plaques provide just enough visual interest without dominating your look.
For those who appreciate Prada's heritage of clean, architectural design and want a frame that balances modern style with long-term wearability, the B11S delivers exactly that. It's the kind of investment piece that justifies its price through years of reliable service and enduring style.
