Our world is a world of the seeing. Only the ability to see allows one to quickly gain an overview of situations, assess their significance, and act accordingly. It is therefore not surprising that parents feel helpless and overwhelmed when confronted with their child's visual impairment. They rightly wonder what this visual impairment means for their child and what implications it carries. Instinctively, they also know that what their child sees does not solely depend on medically measurable values, but also on how they can support their child in optimally using their vision in everyday situations under familiar conditions. The aim of this guide is to provide affected parents with information about visual development and support.
