The "vision test" shows that the visible is an appearance, and the objectivity of vision, as one of the strongest senses of human perception, is broken with the help of visual illusions. As curator Ekaterina Inozemtseva notes: "Avvakumov deftly shuffles meanings, juggles with audience expectations, then almost breaks through to the absolute and, it seems, indisputable, then again shows us such tricks from which we do not really feel powerless — far from it, but ironically accept as inevitable the multiplicity of reality and our perception, layering impressions and meanings."
