| Sumario: | We present a review on the visual ability to discriminate ¿ ne details of moving objects (DVA: Dynamic Visual Acuity), showing the most relevant differences, which have been attributed to this visual capacity in comparison to SVA (static visual acuity). It is known that the correlation between SVA and DVA is low. Moreover, when DVA is measured, not only the minimum spatial separation that the visual system can resolve is evaluated, but also the functionality of the oculomotor system. Therefore, assessing DVA also involves measuring the ability of the eye to actively seek information. Nowadays, it is known that DVA is one of the best indicators of success in certain sports specialties (table tennis, baseball, etc...) and that it negatively correlates with accident rates in traf¿ c scenarios. The investigated factors that produce a signi¿ cant reduction in dynamic spatial resolution are: the speed of the stimulus, affecting both vertical and horizontal trajectories; the stimulus exposure time; ambient illumination; reduction in contrast and subject age. Moreover, it has been veri¿ ed that this visual capacity is likely to improve with training. |
