Model: Eris AKS-508B (PLD-NVY) Gender: Unisex Frame Size (mm): Lens Width Bridge Temple 51 18 140 Frame Material: Hand-brushed finish titanium with double titanium lensrim - side shield, custom titanium temple with round knurling piece,threaded tube screw system and branded titanium temple tip, ceramic w/ beta-titanium nose pad arms Frame Description: For centuries, the world’s greatest orators, poets and novelists have relied on anaphora—the magnetic power of unexpected repetition—in order to convey the strongest of messages and guarantee the most lasting of impressions. Eris, with its innovative co-centered pairing of two titanium frames, makes very clear the lyrical force that lies behind that time-honored concept. While extremely lightweight, Akoni’s Japanese titanium provides exceptional strength, with the side shield’s pattern of circles artistically recalling both the Akoni logo and, once again, the poetic potential of multiples.
