In 2007, the CIN started with 25 principal investigators as cluster applicants, as stipulated in the DFG call for bids. When the CIN cluster was approved further scientists from a range of institutions were incorporated, to make up the 48 'founding members' of the CIN. Since the beginning of 2014 the CIN has consisted of over 80 scientists in total. The membership process involves an application to the steering committee in which the candidate outlines his or her scientific profile and submits a list of publications. The committee's decision is based purely on the scientific excellence of each candidate.

Scientific topic: Eye Growth and Myopia
Field of Research
Although the optics of vertebrate eyes is surprisingly optimized to the visual needs, human eyes tend to grow out of focus in industrialized populations. While genes determine the probability for myopia, visual experience provides the trigger. Using optics, systems analysis, pharmacology, molecular biology, psychophysics and electrophysiology, we try to understand the biological mechanisms of "visual control of eye growth", both in animal models and humans and to suggest strategies for intervention of myopia.
