Cartier CT0637O Cat-eye Optical
Precision, With Grace
The CT0637O captures the timeless femininity of Cartier through a cat-eye silhouette that feels both poised and instinctively powerful.
The lifted lines sculpt the face with elegance rather than sharpness, creating a frame that feels refined, intelligent, and deeply composed. Every curve carries the fluid precision of Cartier design — graceful, controlled, and beautifully balanced.
What makes the frame especially compelling is the subtle jewelry-like refinement woven into its construction. Delicate metal detailing, polished finishes, and perfectly resolved proportions elevate the optical beyond function into something unmistakably luxurious.
Crafted with Cartier’s exceptional savoir-faire, the frame feels light yet precise, allowing comfort and sophistication to exist effortlessly together.
Designed for optical wear, the clear lenses preserve the openness of expression while the silhouette itself adds structure, confidence, and quiet allure.
The CT0637O doesn’t rely on excess to communicate luxury. Like the finest Cartier creations, its beauty comes through restraint, craftsmanship, and timeless elegance.
The result feels feminine, refined, and unmistakably Cartier.
CARTIER — elegance, drawn with precision.

Size and Fit
I understand the importance of a proper fitting frame. Not every frame fits every face, which is why we have a wide selection of frame sizes to choose from.
There are no rules – just guidelines we suggest to help you find frames that not only look great but fit perfectly.
HOW WE SEE YOU
Size definitely matters. We determine size by the width of your face. We offer multiple sizes so that you can find the right frame for your face.
If you already wear glasses, we recommend looking at your current pair as a size reference. If you still have doubt we are here to help you with professional advice.
BRIDGE – INTERNATIONAL OR ALTERNATIVE/ASIAN FITTING
Acetate nose pads: Made from Italian or Japanese acetate. Comfortable, classic fit. Recommended for those who prefer the look of acetate.
Metal nose pads: Made from silicone or ceramic. Soft, flexible, anti-allergic. Recommended for those needing additional support for less prominent nose bridges or more prominent cheekbones.
FIND YOUR FACE SHAPE
Oval
Balanced and slightly narrow, the oval face is a canvas for experimentation. Almost any silhouette will look good on you. Luxury lies in the choice.
Heart
Wide forehead, high cheekbones and a narrow jawline. This shape is expressive and romantic. Choose a sharp-edged or gently curved cat-eye shape or a balanced aviator shape that softens the contrast and emphasizes the proportions.
Square
A strong jawline, higher forehead, and symmetrical brow line characterize this sculptural face. Choose rounded or elliptical frames to soften the angularity and enhance natural strength with graceful restraint.
Rectangle
Long and slender, with delicate lines. Here, it is worth choosing frames that give width and dimension to create harmony. Oversized or deep-set profiles bring visual balance to the more elongated shape.
Triangle
Defined by a more pronounced jawline, a finer forehead, and an elegant contrast between cheekbones. Choose round or square frames with sharp lines that harmoniously balance the proportions.
Round
A full face and delicate contours radiate warmth and symmetry. In contrast, square frames elongate and define the face.
There are no rules – just guidelines. Explore, get inspired and choose frames that make you feel confident, happy and most importantly, yourself.
