Dynamic Visual Acuity

Decent Essays
Vision defines the fundamental way we perceive and respond to stimuli. While static visual acuity for identifying a stationary target is one of the basic visual functions, there are many other important visual functions. In particular, the visual function designed to identify moving targets has been examined by a considerable number of researchers. The dynamic visual acuity (DVA) test, in which scores reflect the difference in visual acuity between stationary and head rotation, measures the individual’s ability to maintain gaze during head rotation. The term “dynamic visual acuity” (DVA) refers to an individual's ability to see clearly during head movement and is a behavioral measure of angular vestibulo-ocular reflex (aVOR) function.
