By providing an open set of tools for creating comparable experiments, our goal is not just to provide a tool, and a set of tools for building more tools, but to provide the basis for one of the world's largest open-science experiments.
Nobody claims to have predictive scientific models of how the visual system works in its entirety, and that means there is still so much more to discover. In the case of Lazy Eye, some aspects of the visual system are de-activated and/or dormant. What we can do is to comparatively explore which techniques and approaches have which effects on opening visual perceptions, and thereby drive our understanding of the system forward on a theoretical and practical level.
