How the frame measurements translate to actual fit

• Using the lens width × 2 + bridge formula (49×2+15), the resulting 113mm total frame width is well below the adult average face width of 120–150mm, so these sunglasses will sit entirely within a narrow face without overhang, giving a clean, tailor-made fit rather than the sloppy look of an over-wide frame on a small face.
• The 146mm temple length sits on the longer side of the standard adult range (135–150mm), which is unusual for a frame this narrow front; it ensures that even wearers with deeper head profiles or those who prefer the temple tips to hook securely behind the ears can get a stable, non-tipping fit without the arms being too short.
• At 15mm, the bridge width falls at the narrow end of the 14–24mm adult range, which is ideal for close-set eyes or a low nasal bridge — this fixed bridge will sit higher and tighter than average on a narrow nose, reducing slide-downs and eliminating the pressure points that wider bridges create on smaller faces.
• At 49mm, these lenses sit at the very bottom of the standard adult small range (typically 47mm–54mm), meaning they are purpose-built for faces that find even 'small' labeled sunglasses still too wide — this is the core measurement that makes them distinguishable from most fashion frames.

The bio nylon frame and its environmental impact

• The frame material is a bio nylon derived from castor oil, a renewable resource that replaces petroleum-based plastics; the castor plant itself is drought-resistant, requires minimal irrigation, and does not compete with food crops, so the raw material carries a low agricultural footprint from the start.
• The frame is designed to biodegrade in approximately five years under landfill conditions, so unlike conventional plastic eyewear that persists for centuries, these sunglasses have a defined and relatively short end-of-life, making the eco claim more tangible than vague sustainability language.

Lens scratch resistance and care over time

• Komono explicitly prohibits using paper tissue to clean the lenses because wood fibers are abrasive enough to micro-scratch the coating, gradually reducing optical clarity; the provided microfiber cloth is the safe alternative that lifts oils without grinding debris into the surface.
• The brand's care rules include avoiding direct sunlight, which is critical because heat accelerates aging in scratch-resistant coatings — lab testing on polycarbonate coatings shows that high-temperature exposure reduces surface hardness, making the lenses more susceptible to scuffs from sand, keys, or accidental drops after prolonged sun or car-dash storage.

How it compares to other eco-friendly sunglasses under €100

• Priced at €69, Lionel brings sustainable bio-based materials down to the cost of many fast-fashion sunglasses, consistent with Komono’s brand mission since 2009 to deliver progressive design at affordable prices.

The retro-futuristic design story behind the Lionel

• KOMONO was born in Antwerp, a city that produced many of fashion's most influential designers, and its eyewear directly channels that heritage—the Lionel's uncluttered lines, precise angles, and refusal to rely on logos embody the 'clean lines, modern feel and innovative materials' that co-founder Raf Maes identifies as the brand's signature Antwerp style, making the frame feel like a museum-shop find rather than a mall staple.
• Founder Anton Janssens has long stated that the brand's mission is to 'make luxury accessible,' and the Lionel at €69 is a direct expression of that philosophy—it delivers an avant-garde, conversation-starting silhouette and advanced bio-based material at a price where most fashion brands would still be using basic acetate, effectively removing the cost barrier between consumer and design-forward eyewear.
• From its 2009 founding, KOMONO has explicitly set out to 'create quality products that combined style with a retro-futuristic slant,' and the Lionel delivers on that brief by simultaneously recalling vintage squared-off sunglasses and sharpening the shape into a contemporary, architectural outline that sits comfortably at a Gen-Z music festival or on a Millennial's brunch terrace.
• For 2025, KOMONO's creative theme is 'Odyssey,' aesthetically inspired by Stanley Kubrick's 2001: A Space Odyssey—a film that crystallized retro-futurism. The Lionel's gently bowed upper lensline and squared-off geometry echo the film's tension between clean future-forward forms and a hint of warm, mid-century optimism, as if the frame were a prop from the Discovery One's wardrobe.
• The frame is made from bio nylon, a castor oil-based polymer that reduces reliance on fossil fuels—this material choice isn't just a sustainability story; it feeds into the brand's futuristic vibe by swapping a classic, glossy petroleum plastic for a matte, tech-forward composite that looks and feels more like a product of the 21st century, aligning the Lionel's tactile experience with its forward-looking design language.
• Both founders were professional snowboarders before launching KOMONO in 2009, and they credit the sport with taking them 'off the beaten track'—that contrarian mindset is baked into the Lionel's design, which subverts the standard square sunglass by introducing a curved browline and a silhouette that feels more like a sculptural object than a purely functional accessory.
• The Lionel's single most distinctive design gesture is the slightly curved upper lensline—a detail that interrupts an otherwise stark square silhouette and introduces a softer, almost mid-century modernist arc; this prevents the frame from reading as aggressive or overly clinical and is the reason the Lionel is described as equally wearable from morning to night, adding a humanist touch to a geometric concept.
