The Theo Isogon 313 is a masterclass in Structural Minimalism, part of the visionary Isolines collection. In cartography, isolines connect points of equal value to reveal the hidden architecture of a landscape; similarly, this frame is designed to act as a precise, mathematical line traced across the map of the face. Crafted from Ultra-Light Stainless Steel, the Isogon 313 achieves a weightless feel while maintaining a bold, squared pilot silhouette that balances industrial precision with Belgian artistic flair.
The architecture of this eyewear is defined by its Bi-Colour Bipolarity, featuring a vibrant “Bluesy Green” and “Elly Blue” front that shifts in intensity depending on the angle of light. With a commanding 58mm lens size and a narrow 13mm bridge, the Theo Isogon provides a tailored Extra-Large fit, perfect for those who want a frame that guides the eye without imposing bulk. The slim, monochromatic black temples are engineered for a low-profile wrap-around fit, ensuring that the focus remains entirely on the geometric complexity of the double-bridge front.
As a dedicated Eyeglasses model, the Theo Isogon 313 is a testament to the brand’s mission to “Color Outside the Lines.” Every frame is handcrafted to ensure durability and a polished, professional finish that works as well in a corporate boardroom as it does in an art gallery. This model is the ultimate choice for the individual who values Cartographic Contour—eyewear that brings structure and individuality to the face through pure, unadulterated line-work.
