... In contrast to the strong synergy of their active responses, the resting states of accommodation and vergence appear to be relatively independent. Individual differences in the dark-focus and tonic vergence are not highly correlated; their average values are significantly different; and adaptive changes induced by optical displacements or near visual tasks can selectively affect either the resting state of accommodation or that of vergence (Owens and Leibowitz, 1983; Owens and Wolf, 1983)

... . The correlation between dynamic and static visual acuities is increased with lower target speeds, binocular viewing conditions, increased exposure durations, and free head movement (DeKlerk et al., 1964; Burg, 1966; Burg and Hulbert, 1961; Weissman and Freeburne, 1965)

... The working group further recommends that a dynamic contrast sensitivity function be measured using grating targets moving with a range of angular velocities, and that it be compared with measurements of static contrast sensitivity function in their relationship to flying ability. Sinusoidal grating targets having the general form of Gabor functions (see Appendix C)
