A comprehensive Sports Vision evaluation can help identify any weaknesses. This factor should be tested in addition to contrast sensitivity, which may be even more critical in athletic performance. Contrast sensitivity measurements give an indication of visual sensitivity to detail and how well the eyes see during different weather and lighting conditions. Dynamic visual acuity is a measurement of how clearly an athlete can see moving objects and should also be evaluated. Two types of eye movements should be evaluated.
Saccades are eye jumping movements when looking from one object to another.
Pursuits are smooth eye movements which are important in tracking moving objects. The speed and accuracy of these skills should be tested. The ability to efficiently change eye focusing and eye aiming when looking between objects at different distances should be tested. Efficient accommodation and vergence abilities are critical for any athlete involved in a sport which requires visual awareness of objects or players at different distances from the athlete. The testing should also probe the athlete's likelihood of visual judgment errors when fatigued or experiencing high levels of stress.
