The latitude/longitude theory of eye movements redefinesthe directionality of eye movements. This new model eliminates false torsions, as found in current methods of quantification, and are the basis for the design of the latitude/longitude goggles. Goggles were designed to measure monocular motor fields in degrees of arc. The measurements in degrees were directly compared to the degrees measured by the arc perimeter. The values obtained from the arc perimeter and the goggles should theoretically agree, but no correlation was found. Correlation was also poor between the goggles and the results obtained from the Hess Lancaster test. The efficacy of measuring motor fields accurately with the latitude/longitude goggles is inconclusive, due to mechanical problems encountered with the prototype. Qualitatively, the latitude/longitude goggles appear to measure monocular motor fields, but with an unacceptably high margin of error. A repeat of this experiment with a better goggle design is suggested.
