Classical theories describing the interaction between blur driven and disparity driven components of the visual motor near triad are examined and the underlying assumptions explicitly stated. Experimental evidence is presented that refutes one necessary assumption behind the traditional structuring of vergence components proposed by Maddox. An alternative theory of binocular interaction is outlined, and experimental support for the new theory is provided.
