Relationship between static and dynamic visual acuity.

Abstract

Research in the area of dynamic visual acuity (DVA) has pointed out a controversy as to the nature of the relationship between DVA and static acuity. This study tried to answer the following questions: (a) Is there a relationship between static acuity and DVA at any speed? (b) If there are relationships at different speeds, are they different kinds of relationships? 30 women, college students, were given 6 speed (20, 60, 90, 120, 150, and 180[degree]/sec) and 1 static measure of acuity. Thresholds for the first 4 speeds were found to show a significant linear relationship with the static acuity thresholds. The relationship disappeared at the highest speed thresholds.
