Quickest turn around time for glasses in NYC
Experience the energy of contemporary French design with XIT Eyewear at Konstantin. Created by eight-time Silmo d’Or award winner Lionel Bellet and produced in Marseille, XIT—short for “Excited”—is known for expressive acetate colors, inventive metal combinations, and bold statement frames that merge modern creativity with refined French aesthetics for customers who appreciate distinctive eyewear.
He went on to become IDC’s artistic director for over a decade, shaping a generation of French eyewear before departing in 2012 to work independently.
In 2015, he launched XIT as a brand in its own right. By that point he had twenty years of design experience, multiple industry awards, and a design philosophy that had never been interested in the safe center of the market: see things differently, or don’t bother.
As an authorized XIT dealer, at Konstantin Vision, we carry XIT eyewear at our NYC showroom for clients who are done with eyewear that disappears.
XIT frames are designed for confirmed personalities — people who understand that what sits at the center of their face can communicate something real. The collection is chic without being predictable, bold without being costumey, and French in the deepest sense: crafted with the kind of precise irreverence that only comes from a designer who has been inside the industry long enough to know exactly which rules are worth breaking.
Our licensed opticians will guide you through the full XIT range — helping you find the shape, material, and finish that fits your face and your character — backed by over 25 years of optical expertise in New York City, with same-day prescription fitting available through our in-house lens lab.
XIT is 100% designed and made in France — and that commitment is structural, not decorative.
The brand is rooted in Marseille, where Lionel Bellet’s studio operates. Production is handled by two specialist manufacturers in Burgundy and the Jura region — the heartland of French eyewear craftsmanship — supporting approximately 48 skilled hands in French workshops, with an additional 12 in design and distribution. This is not outsourced French branding. It is French manufacturing, end to end, in the regions that have defined the craft for generations.
The materials reflect the same standard. XIT works in polished acetate with contrasting inlays, micro-perforated stainless steel, lightweight translucent nylon, and laser-sculpted steel — each chosen for how it behaves in the hand, under the light, and on the face. The FREAKS collection — with its asymmetric round-on-one-side, square-on-the-other silhouette — has become a collector piece. The Les Fleurs du Mal collection features verses by Baudelaire cut directly into the stainless steel face of the frame. These are frames conceived as small works of art — which is precisely what they are.
XIT frames reward the kind of expertise that Konstantin Vision has been building for over 25 years.
Lionel Bellet’s designs play with proportion, asymmetry, and unconventional geometry — which means fit and balance matter even more than they do with conventional frames. Our licensed opticians understand how to align a bold or asymmetric design with your facial structure, how to choose the right prescription lens configuration for an unusual silhouette, and how to make a frame that demands attention feel completely natural to wear every day.
We offer same-day lens fitting through our in-house lens lab, a two-year warranty on frames, and the full benefit of independent optical expertise — not a chain, not a department store counter, but a dedicated NYC optical showroom that takes eyewear as seriously as the designers who make it.
XIT eyewear is available at Konstantin Vision’s Manhattan showroom. Come and see the collection in person — these are frames that need to be tried on to be fully understood.
