The Theo Constantia is a masterclass in refined individuality—a frame that blends geometric elegance with playful artistry. Crafted from lightweight stainless steel, its slender silhouette hovers almost effortlessly on the face, offering a barely-there comfort that lasts all day.

 

Its distinctive oval shape, gently lifted at the outer edges, evokes a subtle cat-eye or butterfly aesthetic. What truly sets it apart is the dual-tone metal construction—two finishes meld to create a living gradient that dances in the light, revealing new character from every angle.

 

Part of Theo's "Characters" collection, the Constantia draws inspiration from classic serif typography—specifically the flowing contours of the printed letter ‘O,’ where bold vertical strokes taper into delicate lines. The result is eyewear that feels both timeless and boldly individualistic.

 

Belgian design meets French craftsmanship in this frame, reflecting Theo's commitment since the 1980s to originality and joie‑de‑vivre. There's a spirited quirk here—enough to spark conversations ("countless times strangers join me in conversation," they've said)  - that retains an air of polished elegance.

 

In each pair of Constantia glasses, you’re not just wearing a frame—you’re carrying a legacy of inventive flair fused with meticulous detail. It’s eyewear that doesn’t just complement your look but defines and elevates it.

It started with a desire we just couldn't deny any longer. It was 1987 and we were hungry. Hungry for ‘a different pair of glasses’. And we were fired up to get to work. Together with Patrick Hoet (designer and anagram-namesake of theo) we decided to create original eyewear for own shops in Antwerp and Bruges.

 

The first theo models we launched made a bit of a splash and enthusiasm is contagious! Colleagues were soon asking us whether they, too, could sell theo in their shops. Little by little and country by country, theo gradually won over more and more hearts. This had an impact on us, of course. It encouraged us to continue on our chosen path.

 

We were increasingly determined to design glasses that always incorporate a touch of humour, individuality and a certain ‘edge’. And we’ve stayed true to this vision. After all, our goal has never changed: together with the theo optician, to make glasses-wearers happy and to offer them an unforgettable experience.

 

Now, a good 25 years later, we’re tremendously proud to be able to collaborate worldwide with a select group of individual opticians who have embraced theo and who, in turn, bring our love for design, originality and quality to their customers.

 

But our story doesn't end here. In the meantime, theo has grown into a platform where designers of all kinds (glasses, fashion, furniture, etc.) can work in synergy with a small army of enthusiastic employees at our warehouse in Antwerp. The drive to keep on inspiring and surprising is simply in our DNA. That, and our love for our fans.

 

theo loves you.
