XIT Eyewear

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.

XIT Glasses in NYC

Lionel Bellet, the designer and founder behind XIT, came to eyewear through theatre and literature before training as an optician and opening his own boutique in Paris. He began designing at IDC — the storied French eyewear company behind the iconic frog emblem — in 1995, winning his first Silmo d’Or barely two years later. 

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.

XIT Eyeglasses at Konstantin

XIT Eyewear represents a fresh direction in contemporary French frame design, with its name derived from the French word “Excitée,” meaning excitement. Established in 2012 by Lionel Bellet and Nathalie Bourgitteau-Guiard, the brand quickly gained recognition as an innovative presence in the luxury eyewear segment. Designed by Lionel Bellet, an eight-time recipient of the Silmo d’Or award, XIT combines vibrant acetate, refined metal structures, and hybrid constructions into a cohesive collection known for originality and technical precision. This strong record of international recognition highlights the designer’s ability to create frames that challenge conventions while maintaining exceptional quality standards.

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.

The Heart of French Craftsmanship
XIT frames are manufactured in Marseille, France, where experienced artisans transform creative concepts into carefully finished eyewear using both traditional and modern production techniques. Producing frames locally reflects the brand’s commitment to preserving French manufacturing heritage while supporting skilled craftsmanship. Each frame demonstrates careful attention to structure, finish, and comfort, reflecting the expertise that has made French eyewear respected worldwide. Marseille remains the creative center where Lionel Bellet’s concepts become distinctive wearable designs.

At Konstantin, XIT Eyewear represents a confident approach to personal style through contemporary frame design. The brand focuses on expressive eyewear that encourages individuality through strong shapes, unexpected color combinations, and innovative construction methods. Collections such as COMBOS, METAL, ACETATE, “FREAKS,” OLDIES, and SUN present different stylistic directions suited to diverse preferences. Whether selecting vivid acetate frames, minimalist metal silhouettes, or mixed-material constructions, wearers can find designs that reflect both personality and modern sophistication.

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.

Why Choose Konstantin for Your XIT Eyewear
XIT Eyewear captures the spirit of modern French elegance through frames designed for individuals who value originality alongside sophistication. The brand successfully merges classic French design principles with contemporary visual language, creating eyewear that feels expressive without losing refinement. From carefully selected color palettes to distinctive construction details, every element contributes to frames that function as both practical vision solutions and style statements reflecting forward-thinking design sensibilities.

At Konstantin, you can explore a thoughtfully selected range of XIT optical frames and sunglasses designed to match both visual requirements and personal style preferences. Our specialists provide guidance in selecting suitable frame shapes and lens solutions tailored to individual needs, ensuring comfort and precision in everyday wear through modern prescription customization options.

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.
