A first in ISSEY MIYAKE EYES collection, the frames in this series are all-titanium metal frames. The style places further emphasis on the “single line” that has been followed by successive series of the collection and continues from the original BONE SERIES, with its strong coloring which emphasized the form. BONE SERIES II, expresses a sense of fun with bright colors; and a new style with a two-tone gradation coated color frame. The baked painting and precious metal plating on titanium make it allergy-free. In addition to the iconic temple design and rim, which appears to be slim from the front yet has significant depth, the colors are reflected, presenting a three-dimensional impression contrasting light and shade while benefiting from the texture of the metal.
