Eyes Right Optical (ERO) and ProDesign Denmark know that great design never goes out of style! To celebrate ProDesign Denmark’s 50th anniversary, the design team at ProDesign Denmark have been going through their back catalogue. It was there they found inspiration for Fill, a refinement of one of their previous bestsellers. Fill is defined by its sophisticated craftsmanship and custom-made acetate lamination. The end pieces are filled with a different coloured acetate, which gives the concept a bold and playful look. The perfect transition line requires a special technique, and this detail makes Fill a refined choice of eyewear.
