The optical brand Silhouette was founded in 1964. It is known for its flexible Titan Minimal Art (TMA) frames, which provide a comfortable and secure fit without creating irritating pressure points. The titanium alloy used in the frames prevents allergic reactions, and the construction of the temples and nose pads weighs only 1.8 grams. This technology is available to NASA astronauts, for whom Silhouette TMA is the first and currently only eyewear chosen for space missions, as well as to anyone who simply wants maximum performance with minimal bulk.
