Phi 1.0 is our SILMO d’Or–winning rimless collection, designed by opticians, for opticians. Reminiscent of the Greek letter ɸ (phi) , the distinctive detail at the heart of our first collection is created by a drill hole centered in a vertically-milled slot. This serves form and function, giving the wearer a wide field of unobstructed vision and the most technically advanced rimless eyewear.
