The film made by the artistic duo of Lucie Rosenfeldová and Matěj Pavlík deals with the phenomenon of phosphene - the phenomenon when variously coloured lights appear in our vision when pressure is applied to our eyes. Based on this remarkable phenomenon, often called inner sight, which has fascinated philosophers, physicians and scientists since antiquity, in their black-and-white imaginative film, the authors reveal how much human perception is influenced by social, cultural and ideological factors.
