ZEN offers exclusive and unique designs in all its frames, for men and women. Every year about thirty models of glasses come out, always betting for minimalism, assuring that they can combine with any individual's style. Zen Barcelona designs may not be corresponding with the fashion trends at that moment, but it is intended so because they do prefer their own style and not to be subject to fashion world's ruling. It is basically a new concept concerning materials. Aluminium provides a higher resistance to the frame and it has got the advantage of not causing allergies as it can happen by using other materials the frames are made of.
