Unisex eyeglasses, made of ultralight titanium, model Isotherm, color 433, orange and black, by the Belgian brand Theo Eyewear, perfectly represent the creative and unconventional spirit that has made the Belgian brand famous in the international eyewear scene. This model combines aesthetic research, structural lightness, and a strong visual identity, transforming eyeglasses into a true design element.
The front, inspired by aviator shapes reinterpreted in a contemporary key, creates a wide yet incredibly light structure. The thin metal lines draw an elegant and dynamic profile, while the orange and black color combination introduces a vibrant contrast that immediately catches the eye. The bright orange highlights the contours of the frame, while the dark details add depth and character to the design.
The minimalist construction makes Theo Isotherm 433 extremely comfortable throughout the day. The thin temples and ergonomic temple tips ensure a stable and light fit, while the adjustable nose pads allow for perfect adaptability to the face. Every element is designed to combine aesthetics and functionality.
Like all Theo creations, this model also stems from a design vision that breaks traditional eyewear patterns. Isotherm 433 is not just a frame, but an accessory capable of expressing personality, creativity, and stylistic freedom.
Available on Più Ottica, with the possibility of customizing the lenses with advanced optical technologies to ensure maximum visual well-being and a completely tailored experience.
