Millenia DX Nocturnal Qx2'DX' means deluxe, and with 'Nocturnal Q II,' you feel the quality the moment you put them on. Theyre even more durable and comfortable than our 'Millenia X2' style, with a stronger frame and a new metal core for enhanced adjustability. They're more scratch resistant, too, thanks to our premium, polarized PureBlend Lens. It all makes for the best feeling, best fitting Millenia shades ever, with a killer matte black aesthetic that matches any fit.
