This is Ivan's marti-rx. It has prescription blue lenses. SIZE 52□19-145 MATERIAL F: TITANIUM T: β-TITANIUM COLOR BK A metal frame with a curved temple and a structure where the temple partially covers the frame. The temple has a new structure that does not directly touch the frame due to the stopper hinge structure designed in 0.1mm increments. No patterns are used on the bridge, rim, or temple, resulting in an extremely minimalist finish. The front combines German design with a teardrop shape and a high bridge, creating a new and fashionable design.
