999.9 (Four Nines)

999.9, read "Four Nines," is a Japanese eyewear brand founded in 1995. Its name comes from the purity mark stamped on bars of fine gold. The brand works from the idea that glasses should be fine tools, so it designs optical frames that are easy to wear, hard to break and easy to adjust, often built around its Gyaku-R hinge. Its lines include 999.9, 999.9 feelsun sunglasses, FN/FOUR NINES, K18 gold luxury frames and CFCL EYEWEAR. It also runs the three-floor Four Nines GINZA store.
