11. Voluntary vergence is also required for viewing autostereograms as well as for voluntary crossing of the eyes. 12. Yarbus showed experimentally that binocular eyes movements are indeed composed mostly of combinations of saccades and vergence . 13. Particular in some places near north Sumatra, where prism toe vergence accompanies with very thick sedimentation. 14. The diplopia was eliminated with and patient had improved positive and negative fusional vergence with decentered glasses. 15. When folds are symmetrical, the vergence tells a geologist only where to find the next antiform or synform. 16. If a number of deformation phases can be recognized in a rock, each phase may have its own vergence . 17. Geometrically the vergence is determined with respect to the up-dip direction of the axial plane of the fold. 18. Vergence is also denoted according to its direction : horizontal vergence, vertical vergence, and torsional vergence ( cyclovergence ).19. Vergence is also denoted according to its direction : horizontal vergence , vertical vergence, and torsional vergence ( cyclovergence ). 20. Vergence is also denoted according to its direction : horizontal vergence, vertical vergence , and torsional vergence ( cyclovergence ).
