| FD | Fixation disparity |
|---|
| vergence | A disjunctive movement of the eyes in which the fixation axes are not parallel, as in convergence or divergence. Origin: L. Vergo, to incline, to turn (05 Mar 2000) |
|---|---|
| vergence of lens | The reciprocal of the principal focal distance used as a measure of the divergence or convergence of parallel rays. (05 Mar 2000) |
| prism vergence test | Measurement of the amplitude of fusion by placing prisms of gradually increasing power in the direction tested until diplopia occurs. (05 Mar 2000) |
| vision disparity | The difference between two images on the retina when looking at a visual stimulus. This occurs since the two retinas do not have the same view of the stimulus because of the location of our eyes. Thus the left eye does not get exactly the same view as the right eye. (12 Dec 1998) |
| retinal disparity | The slight difference in retinal images that arises because of the lateral separation of the two eyes that stimulates stereoscopic vision. (05 Mar 2000) |
| disparity | The condition of being disparate. Origin: L. Dispar, dissimilar (05 Mar 2000) |
| disparity angle | The difference in position of images on the retina, still permitting fusion. (05 Mar 2000) |
| fixation disparity | The amount of heterophoria possible with fusion present. (05 Mar 2000) |
