999.9 (Four Nines) is a Japanese eyewear brand that was born in 1995. Its name originated from the quality indication of pure gold on the pure gold ingot. It’s said that they strive to have a purity of 999.9 out of 1000 which seeks for the highest purity of quality. Using glasses as tools, they have created frames that express high functionality and beautiful form refining the functions required for vision correction devices, such as easy to hang, hard to break, and easy to adjust. Not satisfied with the current situation, 999.9 always seeks for further possibilities and continues in pursuit of the highest purity quality that satisfies our customers.
