The results of optometric analyses are reported to discuss the relationship between adequate visual acuity, efficient state of binocularity, and other abilities required when driving. The results are also supported by the presence of substantial symptoms reported by drivers and associated with these visual performances. Experimental evidence found that the role of visual acuity related to the binocularity, particularly in presence of anisometropia, has consequences on the perception of distances in terms of speed of perception (stereospeed). Significant correlation was also found between visual acuity and both glare sensitivity and light vision. Both eye-hand and eye-foot reaction times were measured, and the presence of limitations of the visual field was found to influence the speed of response to a visual stimulus.
