FLEYE solely  uses nickel-free  quality materials, beta-titanium and acetate, so despite several years of use no allergy can be observed on areas where the frame touches the skin. The materials’ lightness and flexibility as well as a special designed titanium wire for the nose pads support the frame’s comfort and facilitate adaptation of the frame. 

Acetate is a comfortable and nickel-free plastic material from Italy which consists of several layers whereby a unique play of colours and pattern is created. The colours follow the current trends and are inspired by international fashion and fabric fairs.
